Getting rid of bottle

Hi there parents, I need some advice! I'm a FTM and my son just turned one. He's only now starting to have his teeth come in which has pushed my agenda to get him off the bottle. He currently has 3 a day - when he first wakes up, at nap time, and right before bed. Any advice on how to transition away from the bottle and get him used to having his morning milk with breakfast, nap milk with lunch and last one with supper? He gets water with his snacks. He still is trying to get 100% comfortable with his sippy cups. Also he sometimes wakes up at 4am and I give him milk to go back to sleep, counting it as his morning bottle, but if I'm trying to leave that for breakfast I'm not sure how to cut it out?

Sorry if this is all over the place!
