DS is 14 weeks old and for the past three nights has started waking every hour or so during the night! He won't be settled back down until he's been fed (I'm bf'ing him)but it seems like he just wants a comfort feed as half the time he feeds for less than 10 minutes... Any idea what's happening with him? He's never been a great sleeper but this is just horrendous, I'm struggling to cope now after 3 terrible nights
