how to make a kid stop from drinking through his feeding bottle?

My mother gave me some very good advice when my children were little. In our case it was a blanket thing. My daughter could not tolerate being without her blanket, especially at bedtime. I discussed it with my mother one day and this is what she said. "Have you ever seen an 18-year-old with a bottle, pacifier, or blanket?" As kids mature and grow older, the things that they do as children are left behind. One of the only things to be concerned about are baby talk, bad manners, and telling lies. These are things that definitely need to be addressed. I found that I was more concerned about the blanket thing because of what other adults were telling me about the whole thing. I wanted my daughter to appear to be mature and not be laughed at. I think it was more my pride that her feelings in the long run. It did not bother her at all. Before I realized it she had given up the blanket without prodding her or fighting with her. I put the blanket away but have kept it to this day. I think I have more attachment to it now for the memories of it all which will never return again. Funny how many times we want to move along in life only to remember these things as fond memories later.

The previous poster hit the nail on the head; if you don't want him drinking from a bottle at his age, and he really shouldn't be at that age, then stop giving it to him. Let him pick out a "special big boy" cup at the store and make sure that's the only thing he uses. If he didn't want to use the toilet and stay in diapers until he was 6 you wouldn't let him do that either would you? I think it's just a matter of putting your foot down and sticking to it.

It probably doesn't sound like the nicest thing in the world to do. However, I think that since you waited that long to wean your son from the bottle, the only way that you are going to be able to get him to realize that he is too old to be drinking from a bottle is to embarass him. What I mean is that you will have to send it to school with him and that will be all that he has to drink from. When his peers laugh at him he will probably never want to drink from the bottle again.

My younger brother when he was at that age, did not stop yet but when one of his playmates accidentally saw his bottles in the refrigerator and knew that he's the youngest person in our family, my brother stopped immediately because he's afraid of being ridiculed by the other kids. It's best to ask a pediatrician regarding this so that he won't be having any phobias after weaning off the bottle.
