Breastfeeding is best for your baby and provides many benefits.

Breastfeeding is best for babies and provides many benefits. It is important that, in preparation for and during breastfeeding, you eat a healthy, balanced diet. Combined breast and bottle feeding in the first weeks of life may reduce the supply of your own breastmilk, and reversing the decision not to breastfeed is difficult. The social and financial implications of using an infant milk should be considered. Improper use of an infant milk or inappropriate foods or feeding methods may present a health hazard.

If you use an infant milk, you should follow manufacturer’s instructions for use carefully – failure to follow the instructions may make your baby ill. Always consult your doctor, midwife or health visitor for advice about feeding your baby.

Aptamil Pepti 1

Aptamil Pepti 1 is a food for special medical purposes for the dietary management of cows milk protein allergy.

We are updating some of our formulations to meet new EU legislation. Find out more here    

Suitable from birth for the dietary management of cows’ milk protein allergy

Cows’ milk protein allergy (sometimes referred to as CMPA) affects around 2–7.5% of infants, but most will grow out of it by the age of three. The symptoms can be hard to pick up, even by healthcare professionals, but warning signs can include facial swelling, frequent vomiting, regurgitation, diarrhoea, constipation, eczema or respiratory problems like a chronic cough or runny nose.

If your baby has any of these symptoms and has not been diagnosed with cows’ milk protein allergy, you should ask your healthcare professional for advice. It is also worth telling them if you, your partner or any of your other children has a diagnosed allergy as it can increase the likelihood of your baby having CMPA. They may then decide to refer you to a paediatric dietitian for further checks.

When to use Aptamil Pepti 1

Aptamil Pepti 1 is suitable for use from birth and should be used under medical supervision. It is a food for special medical purposes for the dietary management of cows’ milk protein allergy and has been specifically developed for bottlefed babies. Aptamil Pepti 1 contains the same unique blend of GOS/FOS prebiotics as our other milks but it is an extensively hydrolysed formula, which means the cows’ milk protein has been broken down, making it easier for babies to tolerate and digest, whilst providing them with all the nutrition they need.

Benefits of Aptamil Pepti

Aptamil Pepti 1 is part of our special range for the management of CMPA and is the only formula for allergy management. It is whey based for a more palatable taste. It contains our unique blend of GOS/FOS prebiotics. It calso contains LCP's, nucleotides and antioxidents and since babies are unable to produce enough LCPs for their daily needs, we include them in Aptamil Pepti 1 to ensure bottlefed babies with allergies are not missing out.

Aptamil Pepti 1 has been specially tailored by our experts for increased palatability, helping to make mealtimes more enjoyable for your baby again. What’s more, Aptamil Pepti 2 is available for infants from 6 months onwards, making it the best long term solution for babies with CMPA.

Aptamil Pepti have developed a recipe book for parents of babies with cow's milk protein allergy. You can request a copy of this book for free by calling our Careline.

Frequently asked questions

What's in it? Ingredients

What’s in our milk?

Aptamil Pepti 1 is made for bottlefed babies with an allergy to cows’ milk. Its unique formula contains cows’ milk proteins which have been broken down into little pieces (extensively hydrolysed), making them easier for babies to tolerate, along with the same unique blend of GOS/FOS prebiotics as our other milks. It also has a reduced lactose content and, unlike some other allergy management formulas, is based on whey rather than casein. This makes it easier to digest and improves the taste, which may enable your baby to drink more.

What are GOS/FOS prebiotics?

Prebiotic oligosaccharides, often shortened to prebiotics, are special carbohydrates that encourage your baby's friendly bacteria to thrive1,2.

We add a unique prebiotic blend of galacto- (GOS) and fructo- (FOS) oligosaccharides to all Aptamil milks which are derived from lactose and chicory.

Long chain polyunsaturated fatty acids (LCPs)

LCPs are fatty acids, from the omega-3 and omega-6 groups. They are essential for the development of your baby’s brain and eyes and world experts strongly support their inclusion in formulas3.


Aptamil Pepti 1 contains nucleotides, which are the building blocks of DNA – a set of instructions for every cell in the body.

Antioxidants, vitamins and minerals

Antioxidants help protect your baby’s body against cell damage from free radicals. Our nutritionally complete formula contains the antioxidants vitamin C, E and selenium, along with the other essential vitamins and minerals your baby needs, such as iron, calcium and phosphorus.
