So, my son landed in the ER twice around 7.5 months due to severe vomiting and dehydration, both times about an hour after eating peas for dinner. Prior to these episodes, which were 5 days apart, he had eaten and loved peas for several weeks.
The docs did lots of tests b/c they did not believe peas had anything to do with his vomiting. We cut them out anyway and haven't had any severe episodes since. He did eat a green bean and promptly vomited that up several weeks ago, but again, this was after enjoying green bean mush for a week or so. But that was it--I decided not to offer any legumes whatsoever for a while.
He's 10 months now and last night, he wanted some bites of mushroom ravioli. He took a few tiny bites and 30-45 minutes later he began vomiting. Perplexed, we looked at the ingredient list and found pea fiber and pea protein isolate. After vomiting on and off for 2 hours, we were able to get some pedialyte in him and avoid the ER.
Here's are my questions:
1. My ped offered blood allergy testing. But from what I've read online, it sounds very unreliable. Anyone think it's worth it?
2. I realize that he may not be allergic or intolerant of all legumes but I'm afraid to take any chances!! Should I wait 6 months and give him a single lentil and pray he doesn't vomit? I'm really not a gambler...but we're also vegetarians so the idea of avoiding legumes is so foreign to us.
So far vomiting is his only symptom--no skin rashes, diarrhea, etc. Anyone else gone through or heard of allergies like this?
