Cow’s milk protein allergy (CMPA) is one of the most common food allergies in infants1 and it often presents with diverse and non-specific symptoms, making it challenging to diagnose. At Nestlé Health Science, we understand this challenge and are committed to providing expert-developed tools, nutritional solutions and support for healthcare professionals to help facilitate the earlier diagnosis and appropriate management of infants and young children with CMPA. We are also dedicated to providing information, tools and support for caregivers to help raise awareness around the symptoms of CMPA.
Globally, the number of babies with food allergies is increasing

The top eight food allergens in children are milk, eggs, fish, shellfish, tree nuts, peanuts, wheat and soybeans. Over the past 10 years, there has been a large increase in the number of babies diagnosed with food allergies.

CMPA usually develops before a baby's first birthday 

Up to 3 out of every 100 of babies will develop CMPA in their first year of life. CMPA is very rare in children older than 6 years of age.

CMPA usually develops before a baby's first birthday 

Up to half of all babies with CMPA will outgrow it after just 1 year, over three quarters will outgrow CMPA after 3 years, and nearly all babies with CMPA will have outgrown it by their

Babies with CMPA should still be breastfed

In rare cases, breastfed babies can develop CMPA by reacting to cow's milk protein in their mother's breast milk. With changes to the mother's diet, breastfeeding can continue safely. This usually requires qualified dietary counselling to completely exclude all sources of cow’s milk protein from the mother’s diet.

CMPA vs lactose


It is important to know the difference between lactose intolerance and CMPA (also known as CMP), as both have different causes and treatments; In addition, CMPA usually develops early in life, while lactose intolerance is extremely rare before 5 years of age.

The non-specific signs and symptoms of CMPA, ranging from colic and reflux to constipation, insomnia, eczema, diarrhea and crying, make diagnosis a real challenge. The symptoms involve many different organ systems, predominantly the skin and the gastrointestinal and respiratory tracts. The involvement of two or more organ systems increases the likelihood of CMPA.
