Cow Milk Allergy

In most cases children with cows milk allergy will out grow their allergy by age 3-5 years.

Children who suffered from colic, reflux, eczema or diarrhoea, as an infant or young child will in most cases outgrow this in earlier life from 9-12 months, and should be safe to reintroduce dairy. 

It’s important to consult either your doctor or Dietitian to decide if you child is ready to begin reintroduction of milk. Please note though if you child suffers forms severe reactions and/or bad asthma it is safer to complete a formal milk challenge in hospital.

General consensus is to re-introduce slowly starting with baked goods, followed by cultured, then heat treated and finally normal pasteurised cows milk. The success to reintroduction is very individual and some people may never be able to tolerate a glass of milk.

How to begin milk reintroduction:

The UK resource - the milk ladder is particularly useful as a guide.

What to do if your child has a reaction:

Lactose intolerance

Lactose intolerance generally causes symptoms of excess wind, abdominal pain and diarrhoea. Children who have lactose intolerance (inability to digest lactose milk sugar) may tolerate milk products slightly differently as it is not the milk protein causing the symptoms.

Cooking does not necessarily alter the lactose levels. Therefore the focus hear is more on foods such a yoghurt and cheeses where the fermentation of bacteria through processing reduced the lactose levels.

The quantity of the lactose-containing food is of most importance in lactose intolerance.
