I'm not sure what is wrong with my 6 week old. After he has a bottle of his formula, S26 New-Born, he seems to find it hard to let his wind go. I have been using Infacol Wind Drops for the past week and a half and they seem to be helping. At times however he seems to have a really sore stomach, where he will pull his legs up, hold his breath and he acts as though he has indegestion, which interrupts him from going to sleep or wakes him as he starts to doze off. He had his 6 week immunisation on Thursday and it is now Sunday.
