Milk and soya free diets for babies

Why a milk and soya free diet?

Around 3% of children develop Cow's Milk Protein Allergy. Some children who are allergic to cow's milk protein are also allergic to soya protein so this may need to be excluded from the diet too. It can take longer for children to recover, but many 'grow out' of cow's milk and soya protein allergy. This information will help you avoid cow's milk and soya whilst making sure your baby gets all the nutrition they need to grow and develop well.

Which milks should be excluded?

All cow's milk and soys milk including fresh, UHT, sterilised and dried milk should be avoided. The diet should be free of cow's milk protein (casein and whey), milk sugar (lactose) and soya proteins. Other mammalian milks are not suitable alternatives to cow's milk as their protein structure is similar and may still cause an allergic response. Therefore, do not use milks such as goats, sheep, camel and buffalo milk.

Replacing cow's and soya milk

Milk is an important source of nutrition for babies and children. If you breastfeed your baby, ideally continue to do so when introducing cow's milk and soya protein free solids. This is because breastmilk can protect against developing other food allergies. Breastfeeding mothers should also follow a milk and soya free diet (see milk free diet when you are breastfeeding).

If your baby is taking an infant formula, it needs to be a milk and soya free formula.

Suitable infant formula free of cow's milk and soya proteins

Your baby may have been prescribed an allergy formula such a Similac Alimentum, Althera, Nutramigen LGG, Aptamil Pepti (or more rarely Alfamino, Puramino, Neocate or Pepti-Junior). They should continue this until 12 months or as advised by your Health Care Professional.

Most babies aged 6-12 months need approximately 600ml (20oz) each day to ensure they are meeting their nutritional needs, especially calcium. Over 1 year this amount reduces to around 350ml (12oz). These amounts do vary according to the baby and their diet. Check with your Health Visitor or Dietitian if you have concerns about their calcium needs.

Other alternatives to cow's milk and soya milk for cooking

Alternatives to milk that are fortified with calcium are available to buy from most supermarkets. They can be used in cooking from six months of age or as a main drink after one year old.

Examples include: Nuts (Almond, Coconut, Cashew, Hazelnut), Oat or Hemp milks. Brands include Supermarket's own range, Alpro range or Oatly range. Rice milk should not be given to children under 4.5 years old. Always choose a milk alternative that is fortified or enriched with calcium - they should provide at least 120 mg of calcium/100mls. Organic versions do not usually have calcium added - check the label.

Please be aware that some milk alternatives may not be suitable for other allergies and some may be low in calories, protein, calcium and/or other vitamins and minerals. Discuss with your Health Visitor or Dietitian if unsure.

Foods to avoid

Some of the foods to avoid are obvious. However, many other foods may contain cow's milk and/or soya proteins and these should be avoided too. Look for the list of ingredients printed on the package and avoid foods which have 'milk' and/or 'soya' in bold on the label. When eating out, food outlets need to provide you with allergy information by law, so always ask.

Check with your Pharmacist about tablets or medicines which may contain milk or soya proteins and/or lactose.

Introducing solids (weaning)

Starting solids for a baby who has Cow's Milk and Soya Protein Allergy should be the same as for a non-allergic baby, except of course you must not give any foods that contain cow's milk, soya or dairy products. Aim to start around six months, but not before four months (17 weeks). For general information on introducing solids, check the NHS choice website (www.nhs.uk) and type in 'weaning' into the search box.

Adapting recipes

Many ordinary recipes can be adapted by using your milk alternative. Use a milk and soya free margarine instead of butter and milk alternatives in place of milk. Try making up batches of milk and soya free meals/puddings and freezing them in ice-cube trays to allow you to serve small portions with less waste.

What about calcium?

Calcium is needed for strong teeth and bones. Babies under 1 need 525mg/day, 1-3 year olds need 350mg/day
