Not long after our DS turned one, we started offering a snack closer to bedtime instead of a milk sippy, and that seemed to do the trick. He sort of weaned himself off of a bedtime bottle, from there.
DS is 13 months and I'm not stopping his night time bottle for a while. It's basically the only time he gets a substantial amount of milk. He takes sips here and there from the sippy cup but not nearly enough to do without the 8 oz at night. I brush his teeth after the bottle, it's part of our routine.
We've kept the morning and evening cup of milk, just because he loves milk and will fill up on it if we have it at meals. To get it away from immediately before bed, we just started moving it up 5 min every few nights. It's gone from being the last part of his bedtime routine to the first thing in his routine.
