1 year old

first time mom here .. so i’m just wondering what you guys do at night time. my son is 11 months rn he sleeps every night @8 his bottle puts him to bed. and i know he’s supposed to drop the formula and bottle once he hits 1 year. do you guys give your kid milk at bedtime and then they fall asleep? or you give them milk then just let them play or put them in the crib while they’re awake ? my son is always sleeping when he goes down in his crib i’ve always held him and given him his bottle. so idk i just need to figure it out or need advice or some example schedules bc his sister will be here a month after he turns one and i’m stressing 😫
