Baby naps SO good but is awful at night! Help!

My baby will take 3 solid hour and a half to two hour naps during the day. All I have to do is put him on his belly and pat his butt for maybe 10 seconds and he’s out. But at night it’s the total opposite 😭 it takes him so much longer to fall asleep and then when he actually falls asleep, he’ll wake up 30 minutes later and I have to restart the process again. I know he’s not overtired because I follow his sleepy cues and wake windows. What can I do to help him sleep better at night?
