ok, I know some moms will likely object to his, but my ds, who is 3 and a half, still takes a bottle. I dont say it often because people often think I am a bad mother. He takes one bottle at bedtime, gets his teeth brushed and thats it. He LOVES his bottle. ill tell him its time to go to bed and he doestn want to, but he sees his bottle and hes ready. Dr and dentist both know that he takes it and are fine with it, because we are so careful. We have had a ton of transitions since he was born adn are just now settling inot our new home and have adjusted to the new baby, which is why I hadnt taken it away. As long as you are ok with it, and you are careful of his teeth, listen to what you want to do. I know from expreience that with all the changes we had his first 3 years, it was not a good time. Good luck, christie
