Home milk challenge to confirm cow's milk protein allergy

For children with mild to moderate delayed symptoms

It is important to try your baby with milk now. This is to make sure that any improvement in their symptoms is due to cutting out milk (and they have a cow's milk protein allergy) rather than for any other reason.

• Do NOT start this challenge if your child has had either immediate symptoms (within an hour of eating/drinking dairy) or a positive blood or skin test (specific IgE or Skin Prick Test) to cow's milk.
• Do NOT start this challenge if your child is unwell e.g.
  • Has a cold or any other lung infections or breathing problems
  • Any tummy/bowel problems e.g. tummy ache or loose nappies
  • Any 'teething' signs that are upsetting your child
  • Atopic dermatitis (eczema) has flared up
• Do NOT start this challenge if your child is having any medication which may upset their tummy, e.g. antibiotics
• Do NOT try any other new foods during this challenge

Try to write down what your child eats and drinks during the challenge. Also note any symptoms e.g. sickness, loose nappies, rashes or any other changes in their atop dermatitis.
