Only sleeping 3hrs during the day

Hello! My baby is currently 9 weeks and having issues having naps.

He will sleep quite consistently in the night— around 9:30-10pm, a very slight wake up around 12ish, then a bathroom at 4/5am then asleep until 7:30am.

However, during the day he will play for over an hour, once he gets nippy we try and calm him down on the couch, let him doze off w/ us, then put him in the bedroom crate (lights off, cover on). after 15ish mins of whining he’ll fall asleep. But he’ll be back awake only after 40-50mins crying to be let out!

So with all his naps from morning to bedtime only consists of around maybe 3hrs + the 8hrs at nighttime.

Any advice? I always let him go pee right after he wakes up. But should I start ignoring the crying and see if he goes back to sleep?

Thanks in advance for advice!
