My 6 month old may have FPIES and I'm so scared for him.
Last Monday, we gave him his first taste of peanut butter mixed into oatmeal cereal (he had eaten oatmeal a ton of times previously). He also had a bite of avocado which was his second exposure. Everything went well and I put him to bed. Two and a half hours after eating I heard him scream on his baby monitor and put his head back down. It looked like he had fallen asleep again but it was weird that he screamed so I went to check him. He was COVERED head to toe in vomit and limp and disoriented when I picked him up. I yelled at him and he became more alert but continued to vomit several more times. I put him in the bathtub and called the pediatrician on call because I was really scared and he continued to vomit and have diarrhea.
His vomiting finally stopped and he nursed and went back to normal coloring and was happy again. I watched him like a hawk for the rest of the night and didn't sleep, but he was totally fine after nursing and was 100% himself the next day. He never had a fever or anything.
The pediatrician referred us to an allergist and we went on Thursday. He tested negative for IgE allergies to the most common foods and they did a blood test for avocado so we are still waiting for those results. Doctor found that my baby had a double ear infection, so they think that he may have just gotten sick from that. But they also said that the timing was way too suspicious and that they wanted to make sure that he doesn't have FPIES. So now my baby has to go to the hospital in 2 weeks for a peanut butter food trial and potentially an avocado food trial.
I'm so nervous about it and I really hope that he was just sick and that I had the worst timing ever with introducing a new food. Was hoping you guys could share some knowledge, experiences (especially with food trials in a hospital!), and any advice or wisdom. First time momma here and worried sick. Just praying that he doesn't have FPIES.
