Well, my good night looked like this
7:30 - asleep
11:30 - woke, cuddle, BF, back in bed awake,
1:30 - woke, pain meds, BF while they kicked in, back in bed awake
4:45 - woke, cuddle, BF, back in bed awake
6:45 - woke for the day
Our bad nights look more like this:
7:30 - asleep
10:30 - wake screaming, BF to calm, 20-30min cuddle, back in bed awake
12:30 - wake, another 20-30min cuddle, back in bed awake
3 - wake, 45min cuddle complete with arms round my neck to ensure I won't go anywhere (think he's having bad dreams), back in bed awake
4:45 - wake for the day (lies in bed happily til 6:30/7 when I get him up, provided no-one makes any noise or sounds like they're awake)
I find as our naps shrink a bit and the length of the first stretch gets longer, he's starting to self-regulate night vs day sleep better and tends to get close to STTN (and even has a few times) if we stick at the routine. Problem for us is that life has a habit of getting in the way at the moment and setting us back a lot
This from a kid who STTN reliably from 5.5/6 months til 11.5 months... he is an independent sleeper but the developmental stuff is just messing with sleep something chronic since he went through he first language explosion. I can tell the last day or two that he's just come out of a massive mental leap - socially, emotionally, language-wise, everything's gone forward a LOT.
I'm really reluctant to change too much because at least at the moment I'm not dealing with night terrors.
