If she was super OT, IME (and having had a super OT baby at that age), she would be waking frequently in the first few hours of the night. She seems to be getting a good stretch in first thing at night now, then she's waking every 1.5hr... I don't know why. What do you do when she's up during the night? The wakings seem to be quite long to me, but that could be because I had a fast feeder...
She had 14hr in that 24hr period - here's the 'average: (
Typical Amounts of Day and Night Sleep).
1-3 months 15-18 hours Three naps, 1.5 hours each + catnap;
More alert and aware 8 hours at night#
of surroundings; able
to move head
# - This is the longest stretch of night sleep that could be expected before waking for a night feed, and not all the sleep the baby will get at night. Especially in the early days, babies will wake more often for feeding.
So she's a little below the 15-18hr... your instinct is telling you to pull her A time back to an hour or so, yes? If so, give it a go - you know her best.
