We increased awake base on short naps, fighting nap, waking after short nap happy and chilling in crib and waking during the night chilling for up to an hour at a time.
I do think that all of these can be indicators of OT as well, unfortunately. They are more typical of UT, but depending on temperament, she may do all of these things and be OT. Some babies wake happy and some wake upset no matter what.
What happens when you put her down for a nap at 3-3.5hr? Does she fight it, does she wake mid-nap? Short naps can be very developmental from around 3/4/5mo-6/7mo. Both my kids did them and would have kept doing them even if I pushed the A time quite far. I'm just wondering if that might have happened with you or if she's really just a high A time girl. It's possible that the A time has just gotten so high that she's crashing and sleeping through.
I don't see where the nap happened on Tues. You said it was just a one nap day because it was a long one. Could you re-post that for me, please?
Is she a completely independent sleeper? I do think that wake-up after BT is due to OT, and I'm wondering why you're nursing her then, as she's just eaten before BT and it's only been 30min or so. Will she not easily go back down with shh/pat? Even if she was 10-12mo and doing this routine, I would suggest keeping the last A time to around 2-2.5hr, as she's had so much A time already in the day and not a restorative nap (one of at least 1.5hr).
I hope this isn't coming across like I'm thinking you're doing it wrong, I'm really not meaning it to be that way and I don't want to discourage you.
I just haven't come across a 7mo old with a routine like this before, so want to try to get a clearer picture of what's happening.
Oh... posting the same time as you.
What could be causing this?
Honestly, I think she's OT and trying to catch up on sleep. There may be a bit of a nursing prop, but I'm wondering if she just isn't able to get herself back to sleep, because of the OT hormones in her body.
