Milk free diet for breastfeeding mums

Breastfeeding provides the best source of nutrition for babies. Occasionally breastfed babies can react to cow's milk in breastmilk from the mother's diet. This is usually for those babies that have delayed symptoms such as reflux, being unsettled, abnormal stools or severe eczema. For babies that have immediate symptoms to dairy products the maternal diet does not need to change. This dietary advice sheet gives some general information to help you make the recommended changes to your diet and should only be followed for 4 weeks.

If you have any other allergies or medical conditions, please seek further advice.

It is important for you to have a milk free diet, and to avoid major sources of soya. This is because many babies who have delayed reactions to cow's milk also react to soya proteins. Soya can often be tried later to see if your baby reacts to it or not, but it is best not to include it for the first 4-6 weeks. However, do not worry about "soya lecithin" or "soya flour" in products such as bread and sausages.

You will need to avoid cow's milk, soya milk, dairy and soya yogurts, dairy and soya custard, cheese and any products that contain these. Other mammal milks such as goat and sheep are not suitable alternatives as your baby is likely to react to these.

Suitable alternatives to cow's milk and soya milk are: Calcium enriched oat milk, calcium enriched hemp milk, calcium enriched coconut/almond/hazelnut/cashew milks.

Ingredients to watch out for on labels:

There's no need to avoid all products with 'soya' in the ingredients. Only avoid the main source of soya such as soya milk and yogurts, soya desserts and cream, soya cheese and tofu.


When eating out, check with the restaurant or food outlets as they have to provide allergen information by law. As a breastfeeding mum your daily calcium requirements are 1250mg. If this is not met from your diet, then you should take a supplement that provides 1000mg of calcium per day.

If your baby requires a cows' milk free diet then you should be referred to a Paediatrician Dietitian or a trained Health Professional for advice on introducing solids and to ensure you are achieving a nutritionally adequate diet.

What about Vitamin D?

Vitamin D is needed by the body to absorb calcium and the best source is from the action of sunlight on the skin. Vitamin D is only found in a few foods so a supplement is recommended for everyone.
