Allergist

We have an appointment with the allergist tomorrow morning for Alex. Hopefully we'll have some answers sooner than later.
My neighbor suggested that he may be allergic to corn syrup, and I have a feeling he may be allergic to eggs. Yesterday, he threw up after almost everything he ate, and today his pants are really loose around the waste. I have a feeling he is losing weight since we started the soymilk, and I may put him on a soy formula instead. Will update tomorrow with whatever we find out...
