Switching my son to a sippy cup. and learning to fall asleep without a drink. tips please?

What I did with my baby is on her first birthday, I took the bottle away. I just didn't give it to her anymore. It'll be hard for a couple days but after a while they will forget about it. Also try feeding your baby before bed maybe about an hour so that they wont want it but I used the pacifier for my baby up until now she will be 2 in June 1st but with that, she just kept losing them so after she lost the last one which was about a week ago, I haven't bought another one since. So basically just take it away. That really worked for me.
