How does he do with a regular cup?
Does he eat much food? Can you feed him fruit to keep him hydrated when he's not drinking as much?
With the bottle, it would probably work better to wean him off of it slowly instead of trying to make the transition just because he's one.

As for the bottle, there is a suckling instinct until (on average) around 3 I think, so a lot of kids do hold onto those things they would suck on, be they bottles or pacifiers or thumbs, until then. I would be very gentle as he is holding onto it due to an instinct, not just stubborness. Maybe move one feeding from the bottle to a cup, and graudually increase how many times he has a cup instead of a bottle, until it's down to just one bottle before bed. And just that one bottle might not be a big deal - if it gives him comfort you might feel OK letting him stick with that one. I guess I'd just be very gentle. You could even start by giving him a bit in a bottle and then some in a cup to get him used to it. But it might take time, and that's OK. Also, even if he isn't handling it now doesn't mean he might not be more open to it soon. Sometimes it's partly about getting used to the idea of drinking out of a cup, and he'll get more familiar with it the more often you try, even if you just keep trying.
My adopted daughter took a bottle until 28 months! It was her comfort. We eventually gave her water at night instead of milk, then she decided she didn't need it anymore. But we **** gave her a sippy cup of water throughout the night. One year is still so young, I wouldn't push the weaning for quite awhile yet, but that's just me...

Then give him a bottle. It really isnt' a big deal. And if he is currently formula-fed and won't drink cow's milk, continue with the formula. The options are inferior nutrition at this age.
