What do these wake-up’s mean?

I’m at a loss, sleep deprived and depressed pls just help me out lol

Baby f is 10 months tomorrow, yesterday he napped rubbish, had 3 naps- each half an hour.

He usually has 2 longer naps idk why he didn’t then.

Anyway last nap was 3-3:30. Bed at 7:25.

He then woke up at 8, 11 and then 12:30-3 am and then 3:50-4:30 then up for the day at 6:15

What am I doing wrong why is he awake for 3 hours in the night. Every night is such a struggle he’s such a shit sleeper. Any reason u can think he’d be awake this much? He woke up at 5:30 day before
