HELPPPP ME I need sleep lol

So I think we were pretty spoiled with having our daughter as our first baby since she was fairly easy and would actually sleep at night for the most part, but we are however struggling with our baby boy. He will be 11 months soon and has NEVER once slept through the night 😭 We have tried EVERYTHING. He eats a ton throughout the day, we sleep with a sound machine, & we’ve even tried baths before bed and that doesn’t help either. He continues to wake up every 2-3 hours to eat a bottle. Anyone have any suggestions on how to get this child to sleep 😭 I’m looking into a weighted sleep sack but unsure since he refuses to sleep in any position that isn’t on his stomach with his butt in the air lol
