Sleep disruptions??

When did your baby start sleeping through the night? Also did you sleep train them if so how?

I could really use some tips I’m a first time mom. My baby is 10 weeks and he does his last feeding (5oz) at 9:30pm and goes to bed at 10pm. He will sleep till about 2:30am and is on and off till his next feeding at 4:30am. He does a 7 hour stretch which is nice in regards to eating. I took advice from another mom that said she pushed back her baby’s feedings to get their body used to not eating at night. It’s a slow and difficult process but it does work.

My question is my baby does his 7 hour stretch without his bottle but why won’t stay asleep the whole time? He’s just awake wanting his pacifier and getting a little fussy but I know it’s not hunger because he sleeps then wakes up then sleeps and wakes up. This goes on repeatedly till 4:30am when he starts to show his signs of hunger and I already have the bottle ready (5oz). Once I feed him at 4:30 he falls back to sleep until 7:40-8am for his next bottle (4oz) I want him to stay asleep the whole time till 4am. How can I do that? I’m sorry I repeated myself too much lol I made it longer than it should be
