Still wakes up at night

My baby is about to be 7 months on the 17th and he still wakes up during the night. I give him the bottle and he goes back to sleep. I was wondering at what age did your babies fall asleep during the night. Any tips on how I could get him to sleep during the night? He takes naps but for like 15-20 minutes. Through out the day he takes two naps than it’s bed time.
