Question about milk protein sensitivity

My son was never diagnosed with milk protein sensitivity, but I am positive that he is. He was diagnosed with reflux, but meds alone didn't help, and when I cut dairy out of my diet, he started getting better. He weaned at 7 months and has been on soy formula since. He still spits up a lot, but he's off the reflux meds. The pedi encouraged us to introduce yogurt and cheese. He does fine on hard cheeses, but yogurt definitely makes him vomit, big time. Why would cheese be ok, but yogurt not so much? I know some kids take longer to outgrow reflux, but is it possible that he's mildly sensitive to the soy? He never had a problem with soy in my diet while we were BFing.

Re: Question about milk protein sensitivity

  • It almost sounds like a sensitivity/allergy to the whey protein found in dairy. Hard cheeses have very little to no whey protein, the softer the cheese the more whey. The liquid part of yogurt contains whey. I believe you can be allergic to either whey or casein or both.

  • My son has milk protein allergy so i just thought i would share, i hope this helps at least a little!

    there are many proteins in milk including the casein group and whey protein. There are also other parts such as lactose and milk fat. you can also have a milk allergy or milk intolerance. the only way i think to tell the difference between allergy and intolerence is that the immune system is involved in milk allergy. you can get a scratch test to determine a general allergy but i would only recommend it as a last resort. the other test the doc can do to determine an allergy is a "serum IgE to milk protein" this is a blood test and requires blood taken from a vein, which also sucks.

    Here is my experience with milk protein allergy: at 7 months my son had to be hospitalized for an asthma attack (called reactive airway disease at that point) and then at 9 months because treatment was failing (and ONLY for this reason) we got a scratch test, it was pretty rough on both of us :( that is how we determined his original set of allergies, including an allergy to milk protein. it was also recommended that we do the serum IgE (antibody test) but i didnt want to do that to him and the treatment was the same with or without the information: no milk, milk products, nothing containing milk, whey, whey protein, caseins, anything. we did the serum IgE on tuesday of this week because he is now two and I am hoping he has grown out of it. mason always had an asthmatic reaction although i have read that you can get nausea and vomiting as well as colic with the allergy.

     we did not get any useful info through the ped bc they missed all of his symptoms and their misdiagnosis put him in the hospital. we have since switched, but we did take my son to an allergist and he was able to diagnose him accurately in one appointment. my son also has various other environmental allergies (requiring lots of fun and exciting meds) so our case is probably not typical and therefore definitely not meant to alarm anyone.

  • For us I know we had to eliminate all dairy and soy because my LO reacts to both through my breastmilk.  I haven't had the courage to trial him directly yet, the allergist said to try milk and/or milk products directly with my LO after he turned one, but I haven't done it yet.  I'm slowly introducing milk into my diet and waiting for reactions.
    So, I'm not really sure that helps you at all, but I have heard that some kids are fine with dairy products like cheese, but cannot handle milk.  So if your LO is vomitting with yogurt I would definitely avoid that until he is older.  And I would think that your LO would have reacted to the soy formula or soy in your diet if he had an intolerance to it, but unfortunately allergies can develop at any age.

  • Your post matches the experience with my son exactly, however, we never did any reflux meds.  We just met with an allergist to do skin tests, which were all negative.  Now have an appt with a GI doctor.  His symptoms started when he was an infant and have remained, but are not severe, so we have been waiting and hoping that he would just outgrow everything.  At the moment, we are focusing on lactose intolerance.  After the GI doctor, if I still feel I need more information, I am going to make an appointment with a nutrionist.   But to answer your question, all "dairy" items have different amounts of lactose and milk protein.  Plus it can be an accumulation of a few days.  I still have a lot to learn about it.  GL.
