Help!

My bubs is 4 months now, and is yet waking up 2-3 times at night. Goes down at 7:30/8, up at 11pm, 1:30 sometimes again at 2:30 then 4:00am, 5:00am and either wont go back to bed or is then up at 6am. What do I do to ensure he's going through the night.

We tried dream feeding at 11, but then he doesnt go back to bed for another hour and is yet up again at 2:00.

We usually give him the bottle when he wakes and then he falls back asleep.

During the day, 2 long naps

Please let me know what I'm doing wrong.
