Bear in mind I'm still caffienating this morning, but a couple thoughts:
45-minute naps are usually UT, but naps of other odd lengths like 20 minutes are usually OT, if I remember all this. (Been a while since I had a baby in the house.
)
On Sat morning, that first A time - looks like she was awake from 0540 (awake to nurse, so I'm starting there instead of 0555) till 0830, which would be a REALLY long time to be awake. Then asleep for that full hour before the next feed? An hour would be an odd length of sleep cycle, which would lean toward being OT by then. At that age if she's already awake before 6AM, I'd treat that as a NW if I could and try to get her back down straightaway, but if she decided she was up for the day, try for a nap no more than maybe 60-90 minutes later (depends on baby and sleep cues), and then try to extend the nap from there and see if I couldn't get the day on track.
I notice she's waking lots at night, so she may already be waking tired and unable to do a long A time initially, hence being UT at the first naptime, and then ending up OT by the time she does finally give in and fall asleep. Is the Friday feed at 2300 a DF, or is she waking for that?
