Preemie nap schedule

Any other preemie mamas having a hard time pinning down a good sleep schedule?

My boy is technically 6.4 weeks adjusted (4.5 months) but will be 6 months in about a week. the wonder weeks app was more accurate when I changed the dates to a few weeks earlier. So we’re just coming out of the 4th leap and trying to establish our naps and bedtime routine.

He keeps waking up at 11pm. We can get him back to sleep or he will put himself back to sleep without a feed but then he wakes again between 1-2 to eat and then anywhere from 3-5 he’s up talking to himself forcing us out of bed at 5 or 6 am.

Naps during the day vary from 45 mins to 2.5 hours (usually afternoon).

I’m having a hard time trying to work out a schedule and good bedtime but nothing seems to flow and he’s in between that 4-6 months. So he either needs 4 naps a day or 3... I don’t know. I’m confused... if you’re still with me I’m sure you’re confused too 🥴 I’ve gone off wake windows but then I hear some people say to try and stick to a solid routine. But I honestly just don’t think he’s ready for that yet. When he’s ready to sleep he’s out lol.

Any advice from other preemie moms would be appreciated. It’s so hard trying to understand where he is developmentally.
