My 2 week old has just been diagnosed (used loosely) by the paed as having acid reflux. He gave us Nexium to try but didnt really tell us anything about it at all. We started LO on it yesterday - she threw it all up. Take 2 today and she's honestly had her worst day ever. The reflux looks like it has gotten worse - she looks like she's in crazy pain and has been crying nonstop

Any experience with Nexium? Know how long it takes to work? Anything else we can try? DH and I are at our wits end. I just want to cry everytime she cries
We already hold her upright for feeding, keep her upright after feeding, I've started to eliminate dairy and soy.. advice? commiserations? anyone else had experience with this?
