shell - I hear ya on the no sleep, constant comfort feeds all night long!! As you know Nina has been unwell with ear infections and the cold for the past week & half. She was up and down like a yo-yo during the nights with comfort feeds all night long. One night, it was every 2 hours. I too was worried she'd get used to this and it would become habit, but last night in a 10 hour sleep she only woke once, at midnight for a feed. She had last fed at 6pm. Didn't feed again till 7.30am.
I say give her time to get over being sick, also while she's on atiobiotics she may not be feeling her usual self, so will want mummy more. When she's off the antibiotics you'll probably see a difference.
Good luck & HTH.
