I have a call into the pedi, so I'll see what she has to say. Like one of you mentioned, I am thinking of finding a new pediatrician. The problem is, I LOVE the doc herself, but the office is small and stays very busy, so I'm torn. I may not find another pedi I like at an office that's easier to get a hold of.
The soy formula was suggested because when I complained of the gas and fussiness, she asked if either I or my hubbs are lactose intolerant (he is) so she thought the soy would help, and it really has. He is the happiest baby now, as long as he isn't hungry! Whenever he's already had a few bottles but still acting hungry I try other things to make sure that's what it is because I'm honestly astounded at how much he eats. When it comes down to it, if he is truly hungry I don't mind feeding him, but the spitting up has me concerned.
I think it's back to the drawing board because y'all have really given me a lot to think about. I appreciate all the feedback.
