I think we're a bit similar over here :-)
Our 22mo hadn't ever been consistent with sleep. Very spirited and anything new she learns seems to throw her off. Lots of talking, 3 word sentences started, just started part time day care, etc.
We're holding off on PT until we fix the sleep a bit.
Naps are inconsistent, but usually only an hour to 1.5 max. We also go through spells of no nap unless we resort to the car
Nap is after 1:30 on school days (M-R) and we try to keep her up until at least 1p on days at home to be consistent. We stay active with her most of the day (she won't stay still unless strapped into something or held!) and she has slow times to stroll around the block, or read or sit and watch a program around 8am and right after she gets up from nap ~3p.
Currently BT is set at 19:00. She goes down easily now as long as I stay and "sleep" next to her crib until she settles in. I tried wi/wo and she just screamed, for over hour, so this works, kind of.
Every night is different with NW (usually 1, quick resettle if before 3am with sleepy words over the monitor, or sometimes I can go in and say sleepy words and get out pretty easily). She's started saying "hold hand please" when she goes down and when she wakes in the middle of the night *sigh.
EW is every morning and *super* fussy immediately with no recourse but the whole house up lights on reading, snacks, etc. She wakes up immediately and screams Out! Up on mommy! I've tried putting new animals in her bed after she falls asleep, etc.
Usually wakes between 5-6am. This morning 4:47, (but no NW! :-)) no getting her back down, even on me.
She clearly needs more sleep!
We have to car cat nap before day care drop off between 8-9am on days like today, otherwise it all goes south...
Per the pedi recommendation we're trying melatonin before bed and a timer light set at 6am.
Before investing in a gro clock we're trying the led candles we use in the house at night, one in her room set to come on at 6am. Otherwise it's pitch black, which is why I'm scared to get a gro clock to add light to her room...
I'll post back if anything works! :-)
Just need sleep :-)
