Hi T.,
My son was pretty easy to get off the bottle, but a lot of my friends had trouble. I know I started by eliminating the middle of the day bottle, then the morning one and finally the night time one. My son did well with that. Those of my friends who had more difficulty, tried different sippy cups. The Nubi seemed to work well for 2 of my friends. The sports bottle one is shaped most like a bottle. One of my friends her son would only drink from a straw. He never used a regular sippy cup. So try some different kinds of cups. Good luck.
