Cow’s milk protein allergy is of two types.
One is called IGE mediated and the other one is called non-IGE mediated. The symptoms of
IGE mediated are immediately after given milk. They can be in terms of breathing difficulty,
vomiting, and redness of the face. That usually presents within the first week when
the child is given milk. The other type of allergy which is much more
common is called non-IGE mediated allergy. The way you’ll know is if he’s already
has had some feeds in the past and has passed without any problems for the first two to
three months but now has started to develop symptoms like reflux and is vomiting after
every feed, very uncomfortable, has developed a dry skin, and the skin is not getting better
despite putting a lot of moisturizers on it can also have constipation and does not pass
stool for three to four days and every time stool is passed, then it may be very painful,
there may be also some blood in the stools. These are all typical symptoms of cow’s
milk protein allergy. The child definitely needs to be either tested or has to see a
specialist and that has to be confirmed. The way to test is only to avoid giving the child
cow’s milk protein and see if the symptoms resolve.
There are tests available but that will only confirm the IGE mediated allergies. The only
way to confirm non-IGE mediated milk allergy is by avoiding milk. If you are breastfeeding,
then you have to avoid drinking milk yourself. If the child is formula-fed, then there are
special formulas available which do not contain cow’s milk protein.
