My daughter was constantly noisy when lying down, had hiccups at least once after every feed, possetted out her nose all the time, it smelt acidic and in the end it was hurting her. We got gaviscon sachets, started with 4 a day but it was constipating, so reduced it until happy. After 4 weeks we started to cut it out completely. She didnt have it that badly, but once it started upsetting her I went to the drs. Write down symptoms and times through a few days then go asking their advice and suggestions. Often a HV is better to approach first
