How much sleep and how much wake time?

How many hours are your babies sleeping during the night and for naps?

And how long are their wake windows?

My 8 month old will only really sleep about 10 hours at night (once in a while straight through, other times with 1 or 2 wake ups) but I’ve read he needs more like 12 hours.

He also barely gets 2 hours of naps between 2 naps.

I feel like he needs more sleep! But I can’t force him lol

Just wondering if other babies only need about 12 hours total instead of 15

Thanks!
