I have a 7.5 month old baby, who most likely has FPIES. At 6 months, he had reacted with bouts of vomiting 3-4 hours after ingesting bananas, avocados, pears(raw). However, this was all seen on the 2nd or 3rd day of ingesting the same food or after a skip period of 1-2 days.
We got him looked at by a pediatric gastroenterologist, and he does think that my child has FPIES. He asked us to get a ton of tests done, the results of some of which are yet to come. These are not tests for FPIES, but tests to make sure everything else w.r.t. his stools/blood is ok. My son has been ok with oatmeal so far, and we introduced carrots couple weeks ago. He seemed a little uncomfortable during the first 2 days but was fine with it 3rd day onwards. I had a skip period of 2-3 days for carrots. I have now started pumpkin for him, and he seems ok. It has just been 3 days though.
My question is - could I look for some warning signs before the big reaction? I have read that kids have a lot of hiccups, wet burps, spit ups etc. in the days leading to the day of the big reaction. Also, the doctor asked me to give him a new food for 3 days, take a break for 2-3 days, and reintroduce the food for another 3 days. If he passes this test, the food is safe. Do you agree with these periods? Are they too short?
Appreciate any help I could get on these topics. This group has been a savior. Thanks much!
