Flickr Images: How we knew he's allergic to milk! Image source: BADInfluence:
"He was about 6 1/2 months old and my friend decided to give him a taste of
her COW milk and this is what happened! It has only gotten worse since then if
he drinks any regular milk. Funny thing is he can have any other dairy product
with no problem. Only the milk does this in fresh or powder form so no doritos
or cheetos or macaroni."
30-50% of infants allergic to cow milk protein will also be allergic to soy protein. These infants should be given protein hydrolysate formula. 5% of infants with hypersensitivity to cow milk formula will also react to hydrolysate formula and will require elemental formula.
Hydrolysate formulas are enzymatically hydrolyzed and contain charcoal-treated casein or whey. Whey or "milk plasma" is the liquid remaining after milk has been curdled and strained.
