I've had her on coloxyl, she has chronic reflux and is on a medicated formula (Neocate) and I also give her about 1ml of Zantac a day to help and I just don't know - any of the experienced mums out there got any thoughts.
I think you have probably answered your own question. I'm no reflux expert but is she better when she's in he bath? If it is the reflux have you raised her cot a little to help? (prop a rolled up towel under the mattress) You are quite OK to be feeling stressed - it's hard work, especially when they are screaming all the time! Get her to the Dr's and get them to check her out. If it is the reflux they may be able to help a little with something else.
