Asking your opinion on 12 month old?

My son just turned a year old so we are in for some big changes.I want to take him off the pacifier(he only uses it for sleep)he is on whole milk sippy cups but for the last week we have been giving him a night bottle with next step formula this night bottle is such a comfort to him. So I want your opinon how long is it ok to keep giving a night bottle? how old was your baby? Please dont be rude im not asking how to raise my son just what you think.
