Solid foods with MSPI and reflux

tigergirl25

I posted this on my local board, but thought I would ask here as well. My son is 6 1/2 months old who also has MSPI and is on PurAmino and we just started baby food this week. He's been doing oatmeal cereal for about a month now and tolerates it ok for the most part. I started sweet potatoes on Monday and I've noticed the past couple of days, he's been really cranky, and up in the middle of the night with what seems to be a reflux flareup.  Has any others had any experience with sweet potatoes causing the reflux to become bad? What are some good foods to try with reflux babies?
