I strongly agree with Heather L's statement and Lori made a great point as well. My daughter is 15 months and all I have to say is GOOD LUCK! LOL Really, I think you should "phase" it out one at a time (take away one a week). I still give my daughter formula b/c of all the hormones in whole milk. (I will be switching her soon to organic whole milk.) I also agree that you should do what is best for you and your son. I have researched so many ideas on how to get her off the bottle. So, I will tell you everything I have read:
1) Put something that tastes nasty on the nipple and they won't want it anymore. Well, this lady said she put jalepeno juice on the nipple. How cruel! I don't like this idea at all.
2) Dilute the milk with water... add more water each week until they lose interest b/c the milk taste isn't as strong. While doing this make sure he is still getting all the calcium he needs--such as 1/2 cup shredded cheese at lunch, yogurt, cottage cheese, etc.
3) Go cold turkey. This is near impossible for me. I tried actually. I didn't like hearing my daughter (who sleeps through the night every night) cry out every hour b/c of hunger.
4) Tell him/her they are a big boy/girl and have them throw their bottle away (or do it infront of them). Tell them "no more bottle". All I have to say to this one is: Yea, right... maybe if he/she were 2 years old.
Oh, and quite frankly, I am not concerned about my daugther's teeth. I brush her teeth and gums every night and she drinks plenty of water after the bottle to rinse well.
Good luck to you and take your time. YOU are the mom--like another lady said--YOU make your own decisions that fit best in your life and in the needs of your child. Take care.
