Putting baby to bed

So I think we may have spoiled our little baby boy. He’s now 11 months and we have always held him and fed him his bottle till he falls asleep. We are trying to get away from this and having him take his bottle and put himself to bed. It’s been hard and we gave up :/ what age did you have your child do this? I feel like he should be able to do it but at the same time I feel he’s still my little baby
