Exactly that really. My 12 week old has never had a great latch. I've always struggled to get him to open his mouth wider. During the day he always seems to fuss on the boob, I can hear him smacking his lips and swallowing air. This doesn't seem to be a problem at night. He seems much more relaxed and has a better feed, draining both boobs. During the day he snack feeds and it never really feels like he's getting a good amount of milk because of all the fussing. I've tried changing the latch and burping more. Any advice??
He also has really bad smelly farts!! Not sure if that's linked in any way?
