Does 15 minutes really make a difference?

Heya! So I’m trying to figure out if this was a fluke or if 15 minutes of awake time really made a difference. A bit of background.

I have a 22 week old who isn’t formally sleep trained but goes down for naps and bedtime fairly easily (dummy goes in, she falls asleep). We transferred her to her own room at the beginning of the week.

She’s on three naps at 30,~1.5,30 and wake windows are 2.25-2.5/2.5/2.5/2.5-2.75.

The first two nights were rough, she was up every hour and wouldn’t settle back in the cot (note: she had total awake time of around 9.75).

The night before yesterday she had awake time of 10 hrs and ended up going down at around 2020, had a false start but when straight to sleep at 2100, then slept until 2am! Which hasn’t happened in forever!! Fed her and she slept til 0730….

Last night her awake time was just short of 10 hours (9.75) and again, she was up every hour!

So my question is, was it a fluke or did the extra 15 minutes of awake time actually help?!

I’m going to push for 10 hours again today and see how she goes but that last wake window is such a struggle!!! Any tips are appreciated 😅😅😅😅
