Having an allergy to cow’s milk is common in children – it affects about 1 in 50 babies, although most children grow out of it by the time they are 5. A cow’s milk protein allergy can be mild or severe, with symptoms ranging from a rash, swelling on the face, diarrhoea through to severe anaphylaxis.

Speak to your doctor if you think your child may have an allergy to cow’s milk or any other food so that a proper diagnosis is made.

If your child has been diagnosed with a cow’s milk allergy, it is really important to follow advice from your doctor on eliminating cow’s milk protein from your child’s diet. This can be tricky because cow’s milk protein can be present in a surprising number of foods. Most children who are allergic to cow’s milk will also be allergic to milk from other animals, such as goats and sheep.

Eliminating foods that contain cow’s milk protein can make it difficult to ensure children are getting all the key nutrients they need, like calcium, so that they avoid calcium deficiency. Calcium is not only important for strengthening teeth and bones, it is also needed by other parts of the body such as muscles and nerves.

From 6 months of age, children who can’t consume cow’s milk or eat foods containing cow’s milk protein (such as yoghurt and cheese) need alternate sources of calcium and protein in their diets. This is to make sure they have adequate nutrition and healthy growth. Although calcium is found predominantly in milk and milk-based foods, there are plenty of other foods that are rich in calcium such as tofu, broccoli, tinned salmon, sesame paste (tahini) and baked beans. There are also alternative milks that are specifically designed to help children with a cow’s milk allergy get enough calcium and nutrients in their diet – although any dietary changes should only be undertaken with the advice of a healthcare professional.

It can be difficult to keep track of how much calcium your child is consuming and to make sure they are getting enough from the food they eat. This handy calcium calculator can help show you how much calcium is in your child’s diet and tell you if they are reaching the recommended daily intake. It also has a list of foods that are good sources of calcium and can generate a summary that you can print and take to your healthcare professional for advice about calcium deficiency.

IMPORTANT NOTICE: Breast milk is best for babies and provides ideal nutrition. Good maternal nutrition is important for the preparation and maintenance of breastfeeding. Introducing partial bottle feeding could negatively affect breastfeeding and reversing a desicion not to breastfeed is difficult. Proffesional advice should be followed on infant feeding. Infant formula should be prepared and used exactly as directed or it could pose a health hazard. The preparation requirements and weekly cost of providing infant formula until 12 month of age should be considered before making a decision to formula feed.

Mothers should be encouraged to continue breastfeeding even when their infants have cow's mil allergy. If a decision to use an infant formula for special dietary use is taken, it must be used under medical supervision.
