Is she finishing her feed during the night feeds? Or falling asleep? Maybe she's not getting her full feed during the night if she's falling asleep?? DS used to fall asleep halfway through and then wake a couple of hours later- I started tickling his feet a little, so he'd wake up just enough to finish his feed, and if he woke up a little, he'd zonk out again soon with a full belly.

Sorry, not much else in my repartee!!! Except for a double feed before bed. Bedtime for him is between 6-7 and he usually has a feed at 4.30ish and then another just before he goes to bed. (He often zonks out at the second feed).
