My son is 8 months and 2 weeks and still having trouble sleeping throughout the night

Before I was putting him to bed the latest 8:30pm, and he was waking up at 7-7:3am. Throughout the night he would wake up but if I just pulled my boob to the side, he would go right back to sleep. Since I’m breastfeeding and he’s more feeding for comfort I’m doing this what seems like all night but it only last about 5 minutes and he goes right back to sleep.

This week I changed his bed time to 7pm to see if he would sleep better. He’s still cluster feeding but now he’s waking up fully between 4-5am and he’s up for about an hour/ 1.5 and then goes back to sleep then wakes up at 7-7:30am.

Any suggestions on how to keep him asleep or is anyone else dealing with this issue ? He still doesn’t know how to put himself back to sleep either. If I just let him lay there in the dark he’ll just roll over and start wanting to play. Help ! I’m thinking maybe going back to the 8:30pm bedtime since at least he staying up for over an hour 😫

My SO works from 1:30pm-4am Monday-Sunday. I’m basically doing everything myself and I would like to at least get some kind of sleep

* He’s been cluster feeding since he was born. I’m trying to get him out of that pattern that’s why I changed his bedtime. I was told I was keeping him up too late which was making him overtired
