I had the low amniotic fluid during pregnancy too. I wish my dentist hadn't passed off my complaints of canker sores as hormonal. Although I take most of the blame because I'm notorious for avoiding doctors so until I was dealing with daily nausea I didn't discuss my annoying symptoms with doctors earlier... Even then I had to ask for the celiac testing as I was told reflux, gall bladder, IBS... I am hoping as awareness increases fewer people have to suffer with these symptoms for years.
So sorry you're feeling down. I keep telling myself this will become the new normal in due time for not just myself but my family as well. I'm also waiting for that day because I still seem consumed by it.
I would think there are some kind of standards that the kitchen must abide to in order to serve children with allergies. Do they have a list of safe foods that can be provided to you to make sure your outside food fits in with the guidelines of what is allowed in the center (no peanuts, etc)?
