K.C.
I do it by over a couple of days switching the bottle with something else, sippy cup of Nubby or whatever you choose. don't let it last more than a week.
Someone ignorant once advised me to have the child throw the bottle in the garbage, that to me seems heartless and unnecessary. Why would you have a baby through something he loves in the garbage? It is no different than having him throw his puppy or blanket or whatever else he's attached to in the garbage never to be seen again, it's all the same to him! Don't recommend that one!
