Needing some advice!

So my baby was sleeping through the night until 4 months old and then suddenly he started waking multiple times a night like 5-6 times. It’s been almost two months now and he’s still doing it. He wakes, nurses for maybe 10 min each time and then goes back to sleep. I noticed he seemed like he was trying to move around and roll over while trying to sleep and his halo sleep sack seemed like it was preventing it so I bought him the sleeping baby zipadee zip sleep sack. That seems to have helped with the trying to move around but he’s still waking 5-6 times a night. Anybody have any ideas on what I can do to help him sleep? Two months of no sleep is creating one tired momma 😴 I’m not against sleep training but if we did that it’d have to be done in our room still since when he goes into his room he will be sharing a room with my daughter and I don’t want to keep her up while trying to sleep train him. Any advice would be helpful! Thanks!
