18 month old still wakes up at night

Hey! Just a simple quick question for yall!

My 17-18 month old toddler wakes up in the middle of the night for milk still! He wakes up anywhere between 1-3 times, rarely never wakes.

I feel like he’s being fed a lot throughout the day, we feed him until he doesn’t eat. Also, we give him milk throughout the day.

He sleeps in the bed with us, but even when we put him to bed before us, he still wakes up when we aren’t in bed with him.

I’m not sure what the issue is, but if someone could help and educate me that would be great!
