How many hours does your 20 month old sleep now?

There is no sleeping through the night to us. My babe goes to bed 7:00pm and wakes up multiple times a night like he was when he was younger. Not sure if this will ever change? We are co-sleeping and I just recently weaned him from his water that causes him to wake up multiple nights. Does your babe still wakes up in the middle of sleep? He wakes up sometimes screaming “Mama” not sure if he is dreaming or he can’t feel me next to him even though we are sleeping on one bed.
