For her third birthday, we decided that it was time for Avery to give up her bottle. (Yes, we are such hard-asses -- that's only two years after most kids give it up. And especially entertaining since she moved out of her crib early, spoke early, was toilet trained early, etc. The bottle was kind of the last bastion of her babyhood.)
On her birthday (and after talking about it every day for a few weeks), we got rid of her changing pad, her gate on her bedroom door, and the night time bottle. She was pretty good about it, but did wake up in the middle of the night asking for it on the first night. I soothed her and reminded her that we had made a mutual decision to give up the bottle since she was now a big girl. I offered to get her a sippy cup of milk instead of a bottle...and she said to me, "Life is hard with a sippy cup."
It is, my little angel, and sometimes Jimmy has diarrhea. These are good lessons to learn early in life.
