How to get my lo to sleep at night

Cassie • 🎉🎃🍁🍂 blessed with a beautiful 3 year old boy a 2 year girl and a 9 week girl👨‍👩‍👧‍👦
Since my lo was born 4 weeks ago he's got a habit of wanting to sleep on me all day and night but during the night every time I go to put him in his Moses he wakes up and starts crying anyone know how to shift this, also he wakes every 2,3 hours for a feed and most of the time he takes a full 4oz bottle but then his next feed he will take 1oz or 2 and pass out on me go to put him to bed and he wakes again, I need my sleep at night as I don't want to be sleeping through the day. Any helpers know how to get him to sleep all night instead, btw I did try breastfeeding but he couldn't latch properly so is formula fed now xx
