So up until a few days ago my baby girl was super content: she'd feed, be awake and happy for a little while and then sleep. She had just started sleeping for 5/6 hrs a night. She's exclusively breastfed and putting on weight so everything going well! But the past few days have been a completely different story. She's waking up every couple of hours to feed, and afterwards still chewing her hands, really unsettled and seems to always be hungry. I don't feel like my milk supply has caught up because my boobs always feel empty! Does this sound normal?? I'm really battling with the idea that we might have to top up with formula but I have no idea what the right thing to do is!
