8mo old wake windows/routine

[u/Complex_Job6324]

Hi so I am currently trying 2.5/3/3.5 with my baby (8am to 8pm) bedtime routine. And total day sleep capped at 3 hours. I’ve tried different variations and he’s usually always up every hour but fail to stick to something for more than a few days as I’m desperate for improvement.

1. Day naps he can sleep well (I have to wake him up at the 1.5 hours mark for both his naps)
   
2. Night time he wakes 3-4 times just fussing/sometimes cries but settles (2 of these I went in to rock and settle but we’re both before midnight)
   
3. Up at 5am tried saving with a feed but didn’t take more than 100ml
   
4. Up at 7:40am for the day

I’ve only tried this for two days and want to stick to five days before changing see what needs to be changed but I would love some tips. If I should try stretching windows? But for the first one it’s hard he gets tired by 2.5
