What Is Aptamil 1 First Baby Milk Formula and Is It Right for Your Newborn?

 

Choosing how to feed your newborn is one of the most important decisions you'll make as a new parent. The NHS recommends breast milk as the best source of nutrition for babies, but it also recognises that breastfeeding isn't always possible or the right choice for every family. When that's the case, a first infant formula is the only suitable alternative for babies under six months old. Aptamil 1 first baby milk formula is one of the most widely used options in the UK, offering a nutritionally complete feed designed to support your baby's growth and development from the very first day. You can find it alongside other trusted products in our baby and toddler range at Cured Pharmacy.

This 800g tin provides a generous supply, making it a practical choice for parents who want to stock up without running out at inconvenient moments. Each tin is formulated to meet the nutritional requirements set out in UK and EU infant formula regulations, so you can be confident your baby is getting what they need.

 

How Does Aptamil 1 First Baby Milk Formula Work to Nourish Your Baby?

 

Aptamil 1 is designed to provide complete nutrition for newborns by combining a carefully selected blend of ingredients that work together to support healthy development. Here's how the key components contribute:

  • Whey protein: The formula uses a whey-dominant protein blend, which is closer in composition to breast milk than casein-dominant alternatives, making it easier for young digestive systems to handle.
  • Lactose: The primary carbohydrate source, lactose mirrors what's found naturally in breast milk and supports energy needs.
  • Vegetable oils: A blend of oils provides essential fatty acids, including linoleic acid and alpha-linolenic acid, which support brain and eye development.
  • GOS/FOS prebiotic blend: Galacto-oligosaccharides and fructo-oligosaccharides are added to support a healthy gut environment, inspired by the prebiotic components found in breast milk.
  • Vitamins and minerals: Including iron, calcium, vitamin D, and vitamin C, all at levels appropriate for infant nutrition.

Together, these ingredients are formulated to meet the complete nutritional needs of a healthy, full-term baby from birth to around six months, or alongside weaning foods up to 12 months.

 

Who Should Use Aptamil 1 First Baby Milk Formula?

 

This formula is intended for healthy, full-term babies from birth. It's suitable as either a sole source of nutrition or as a supplement to breastfeeding. That said, it isn't appropriate for every baby — always speak to your GP, midwife, or health visitor before starting any infant formula, particularly if your baby has specific medical needs.

  • Babies from birth up to 12 months who are not being breastfed, or where breastfeeding is being supplemented
  • Full-term, healthy newborns without diagnosed cow's milk protein allergy or lactose intolerance
  • Families transitioning from breastfeeding who need a nutritionally complete alternative
  • Parents looking for a widely available, regulated first infant formula

It is not suitable for premature babies, babies with cow's milk protein allergy, or those with galactosaemia. If you're unsure whether this formula is right for your baby, your health visitor is the best first point of contact.

How Should You Store Aptamil 1 First Baby Milk Formula?

 

Proper storage is essential for keeping the formula safe and effective. Store the unopened tin in a cool, dry place below 25°C, away from direct sunlight. Once opened, keep the lid tightly closed and use the contents within four weeks — even if the best-before date hasn't passed yet. Never store the tin in the fridge once opened, as moisture can affect the powder.

Prepared feeds are a different matter. Once you've made up a bottle of Aptamil 1 first baby milk formula, it should be used within two hours if kept at room temperature, or within 24 hours if stored in the back of the fridge (not the door). Never reheat a feed that has already been partially consumed. If you're looking for other health essentials for your family, our vitamins and supplements collection includes a range of products to support parental wellbeing too.

This product is a food for special medical purposes. Speak to your doctor, midwife, or health visitor before use if your baby has an underlying medical condition or specific dietary requirements.

Specifications of Aptamil 1 First Baby Milk Formula From Birth 800g

 

What Is Aptamil 1 First Infant Formula and What Is It Used For?

 

Aptamil 1 First Baby Milk Formula is a nutritionally complete first infant formula suitable from birth. It is intended to be used as a substitute for, or supplement to, breast milk when breastfeeding is not possible, insufficient, or not chosen. The NHS is clear that breast milk is the optimal food for babies, but where that isn't an option, a regulated first infant formula like this one provides the nutrients a newborn needs to grow and thrive.

The formula is designed to be used from birth up to 12 months of age. It can be used as the sole source of nutrition for babies under six months, or alongside solid foods during weaning from around six months onwards. It is not a follow-on formula and should not be confused with Aptamil 2, which is intended for older babies.

 

What Do You Need to Know Before Using Aptamil 1 Formula?

 

Before starting any infant formula, it's important to understand when it may not be appropriate. The following contraindications and warnings apply:

  • Do not use if your baby has been diagnosed with cow's milk protein allergy (CMPA) — seek specialist formula advice from your GP or paediatric dietitian
  • Not suitable for babies with galactosaemia or glucose-galactose malabsorption
  • Not suitable for premature or low-birth-weight babies without specific medical advice
  • Do not use as a replacement for breast milk without first discussing with your midwife, health visitor, or GP
  • Always prepare feeds using freshly boiled water cooled to no less than 70°C to reduce the risk of bacterial contamination
  • Never add extra scoops or dilute the formula — always follow the preparation instructions exactly
  • Do not use if the tin seal is broken or damaged on purchase

Regarding interactions — infant formula is a food product and does not interact with medicines in the way pharmaceutical drugs do. However, if your baby is prescribed any medication, always check with your pharmacist or GP about timing around feeds. You can also browse our vitamins and supplements section if you're a breastfeeding parent looking for nutritional support for yourself.

 

How Should You Prepare and Use Aptamil 1 First Baby Milk Formula?

 

Correct preparation is critical for your baby's safety. Powdered infant formula is not sterile, so following these steps carefully every time is essential.

  1. Wash your hands thoroughly with soap and water before preparing any feed.
  2. Sterilise all feeding equipment — bottles, teats, and caps — using a steriliser, boiling water, or sterilising solution.
  3. Boil fresh tap water (not filtered or bottled) and allow it to cool for no more than 30 minutes, so it remains at or above 70°C.
  4. Pour the correct amount of water into the sterilised bottle first.
  5. Using the scoop provided, add the exact number of level scoops required — do not heap or pack the powder.
  6. Replace the teat and cap, then shake the bottle well until the powder is fully dissolved.
  7. Cool the feed to feeding temperature by holding the bottle under cold running water or placing it in a bowl of cold water. Test the temperature on your inner wrist before feeding.
  8. Feed immediately and discard any unused formula within two hours.
Baby's Age Number of Feeds per Day (approx.) Water per Feed (ml) Scoops per Feed
Birth – 2 weeks 6–8 60–90 ml 2–3
2 weeks – 2 months 5–7 90–120 ml 3–4
2–4 months 5–6 120–150 ml 4–5
4–6 months 4–5 150–210 ml 5–7

Feed volumes are a guide only. Every baby is different — always feed on demand and follow your health visitor's advice. Never force your baby to finish a bottle.

 

What Are the Possible Side Effects of Using Aptamil 1 Formula?

 

Aptamil 1 is a food product, not a medicine, so it doesn't carry a traditional side effect profile. However, some babies may experience digestive changes when starting or switching formula. These are usually temporary.

Common digestive responses:

  • Wind or flatulence
  • Loose or more frequent stools
  • Harder stools compared to breastfed babies
  • Mild colic-like symptoms
  • Posseting (small amounts of milk brought up after feeds)

Less common or more concerning signs — seek medical advice if you notice:

  • Persistent vomiting or projectile vomiting
  • Blood or mucus in stools
  • Skin rash, hives, or eczema worsening after feeds
  • Excessive crying or apparent pain after feeding
  • Swelling of the lips, face, or throat (seek emergency help immediately)
  • Failure to gain weight as expected

If you're concerned about any of these signs, contact your GP or health visitor promptly. Don't switch formulas without professional guidance, as this can sometimes make things worse rather than better.

 

How Should You Store Aptamil 1 First Baby Milk Formula Safely?

 

Safe storage protects both the nutritional quality and the safety of the formula. Follow these guidelines carefully:

  • Store the unopened tin in a cool, dry place below 25°C — not in the fridge
  • Once opened, keep the lid tightly closed and use within four weeks
  • Do not store opened tins in the fridge — moisture can cause clumping and contamination
  • Prepared feeds should be used immediately or stored in the back of the fridge (not the door) and used within 24 hours
  • Never freeze prepared formula
  • Do not use formula past its best-before date
  • Keep out of reach of children

Frequently Asked Questions

Where can I buy Aptamil 1 First Baby Milk Formula online in the UK?

You can buy Aptamil 1 First Baby Milk Formula 800g online from Cured Pharmacy at £15.80, with convenient delivery to your door. It's also available from supermarkets and high street pharmacies across the UK. Buying online can be especially helpful when you need to stock up without leaving the house with a newborn.

How does Aptamil 1 first baby milk formula work in the body?

Aptamil 1 provides a complete nutritional profile through a blend of whey protein, lactose, vegetable oils, and GOS/FOS prebiotics that together support your baby's growth, brain development, and gut health. The whey-dominant protein is easier for young digestive systems to process than casein-heavy alternatives. The prebiotic blend helps support a healthy gut microbiome, inspired by components naturally found in breast milk.

How do I prepare Aptamil 1 formula step by step?

Boil fresh tap water and allow it to cool for no more than 30 minutes so it stays at or above 70°C — this temperature is important for killing any bacteria in the powder. Add the correct number of level scoops to the water in a sterilised bottle, shake well, then cool to feeding temperature before offering to your baby. Always discard any unused formula within two hours of preparation.

What is the correct amount of Aptamil 1 to give a newborn?

As a general guide, newborns typically need around 150–200 ml of formula per kilogram of body weight per day, spread across multiple feeds. In the first two weeks, this usually means 60–90 ml per feed, six to eight times a day — but every baby is different. Always follow the feeding guide on the tin and take advice from your health visitor, as they can tailor guidance to your baby's individual needs.

Can Aptamil 1 cause wind or colic in babies?

Some babies do experience wind, flatulence, or colic-like symptoms when starting any formula, and this is usually temporary as their digestive system adjusts. The GOS/FOS prebiotic blend in Aptamil 1 is included to help support gut comfort, but it won't eliminate wind entirely in all babies. If symptoms are severe or persistent, speak to your GP or health visitor rather than switching formula without guidance.

Is Aptamil 1 suitable for premature babies?

No — Aptamil 1 is designed for healthy, full-term babies from birth and does not meet the specific nutritional requirements of premature or low-birth-weight infants. Premature babies often need specialist preterm formulas with higher calorie and protein content, which should only be recommended by a neonatal healthcare team. Always seek medical advice before feeding a premature baby any formula.

How does Aptamil 1 compare to Aptamil 2 follow-on milk?

Aptamil 1 is a first infant formula suitable from birth, while Aptamil 2 is a follow-on formula intended for babies aged six months and over who are also eating solid foods. The NHS advises that first infant formula is the only suitable alternative to breast milk for babies under six months — follow-on formula is not necessary and should never be given to younger babies. You can browse our baby and toddler range for more infant feeding products.

How long can I use Aptamil 1 for?

Aptamil 1 can be used from birth right through to 12 months of age, either as a sole source of nutrition or alongside solid foods during weaning from around six months. After your baby's first birthday, full-fat cow's milk can be introduced as their main drink. There's no need to switch to a follow-on formula — first infant formula is nutritionally appropriate for the full first year.

Can I mix Aptamil 1 with breast milk?

It is generally not recommended to mix formula directly with expressed breast milk in the same bottle, as any leftover feed would need to be discarded, potentially wasting valuable breast milk. Instead, you can offer breast milk and formula in separate feeds. If you're considering combination feeding, speak to your midwife or health visitor for personalised guidance on how to manage this safely.

What should I do if my baby refuses Aptamil 1 formula?

Formula refusal is common and can be related to teat flow, feed temperature, or simply your baby's preference — it doesn't necessarily mean the formula is wrong for them. Try adjusting the teat size, ensuring the feed is at a comfortable temperature, and offering feeds in a calm environment. If refusal continues or your baby isn't gaining weight, contact your health visitor or GP for support.

Is Aptamil 1 suitable for babies with cow's milk protein allergy?

No — Aptamil 1 contains cow's milk-derived proteins and is not suitable for babies with confirmed or suspected cow's milk protein allergy (CMPA). Babies with CMPA require a specialist hypoallergenic or amino acid-based formula, which should be prescribed or recommended by a GP or paediatric dietitian. If you notice signs of allergy such as skin rashes, vomiting, or blood in stools, seek medical advice promptly.

How should I store Aptamil 1 once the tin is opened?

Once opened, keep the tin tightly sealed and store it in a cool, dry place below 25°C — not in the fridge, as moisture can cause the powder to clump and become contaminated. Use the contents within four weeks of opening, even if the best-before date hasn't passed. Never transfer the powder to another container, as this increases the risk of contamination.

What are the alternatives to Aptamil 1 first infant formula?

Other regulated first infant formulas available in the UK include SMA Pro First Infant Milk, Cow & Gate First Infant Milk, and HiPP Organic First Infant Milk — all of which must meet the same UK nutritional standards as Aptamil 1. The NHS advises that all first infant formulas are nutritionally equivalent, so the choice often comes down to your baby's tolerance and your personal preference. If you need support choosing, your health visitor or pharmacist can help. You can also explore our vitamins and supplements range for postnatal support products.

What are the latest guidelines on infant formula preparation in the UK?

The NHS and the Food Standards Agency (FSA) recommend preparing formula with water that has been boiled and cooled to no less than 70°C, as this temperature is sufficient to kill harmful bacteria such as Cronobacter sakazakii that can occasionally be found in powdered formula. Feeds should be made fresh for each feed where possible, rather than made in advance. The NHS guidance on formula preparation is regularly reviewed and updated — always check the NHS website for the most current advice.

How do I know if Aptamil 1 is meeting my baby's nutritional needs?

The clearest signs that your baby is getting enough nutrition include steady weight gain along their growth centile, regular wet and dirty nappies, and a generally settled, alert demeanour between feeds. Your health visitor will monitor your baby's growth at regular checks using the Personal Child Health Record (red book). If you have any concerns about your baby's growth or feeding, don't wait — contact your health visitor or GP for reassurance and support.

How Should You Use Aptamil 1 First Baby Milk Formula?

Preparing infant formula correctly every single time is essential for your baby's safety. Powdered formula is not sterile, so the preparation method matters just as much as the formula itself. Always wash your hands thoroughly before you begin, and make sure all feeding equipment has been sterilised.

Follow these steps for every feed:

What Is the Correct Dose of Aptamil 1 First Baby Milk Formula?

Feed volumes should always be guided by your baby's age, weight, and appetite. The table below provides a general guide — but remember, every baby is different. Never force your baby to finish a bottle, and always feed on demand. Your health visitor is the best person to advise on the right amount for your individual baby.

When Is the Best Time to Use Aptamil 1 First Baby Milk Formula?

Infant formula should be offered on demand — that is, whenever your baby shows signs of hunger such as rooting, sucking on their hands, or becoming restless. Newborns typically feed every two to three hours, including through the night, and this frequency gradually reduces as they grow. There is no fixed schedule that suits every baby, so responding to your baby's hunger cues is always the right approach.

If you're combination feeding — offering both breast milk and formula — your midwife or health visitor can help you plan a feeding routine that works for your family without compromising your milk supply.

How Long Can You Use Aptamil 1 First Baby Milk Formula For?

Aptamil 1 is suitable from birth up to 12 months of age. It can be used as the sole source of nutrition for babies under six months, and alongside solid foods during weaning from around six months. After your baby's first birthday, full-fat cow's milk can replace formula as their main drink, provided they are eating a varied diet. There is no clinical need to switch to a follow-on formula — first infant formula remains nutritionally appropriate for the entire first year.

Do not exceed the recommended dose. If in doubt, speak to your pharmacist.
