My baby is nearly 8wk old we've had issues with formula crying straining gipping sneezing etc we changed to comfort milk (advised by gp) and infacol no change then she started being sick so was told maybe an allergy so moved to lactose free milk we've been on it a week yesterday. I thought it was working she seemed loads happier until yesterday! She's straining. Smells farts and I've changed more poop nappies in the last 24hrs than I have in her 8wks of life!! 10mins ago she literally coughed and did abit of poop. It's runny stinky and either green or yellow!

I'm thinking maybe the lactose free milk doesn't agree with her? With the other milks she had abit of stinky farts and the odd runny nappy every other day or few days
