Breastfed almost 9 month old still wakes up multiple times at night

Ch

Help! Idk how to get my baby boy to sleep through the night. He will wake up and want nursed back to sleep at least 2-3 times at night. I know my supply is going down since he eats baby food, too but it doesn’t seem like he isn’t getting enough milk from me...at least I hope that’s not the case. I’m just so tired, and my husband works 3rd shift so it’s just me at night.
