Hi we have recently had to change my 15 week old son to lactose free formula he's been on it 3 weeks now doesn't seem to be screaming in pain anymore but this last week or so has decided to refuse the bottle he will sleep feed a whole 150ml but I can't always do that as he's awake alot more now. I have tried different positions techniques nothing seems to work I don't know what else to do. Has anyone got any advise please? Desperate right now just need him to take the bottle again
