A.E.
When my son turned one, I packed up the bottles so I wasn't tempted to give him one. We started using the soft-nippled sippy cups right away. Maybe if there's no option of a bottle, your son will start using a sippy cup. We also found that my son loved ALL kinds of water bottles so you might try that as well.
As for potty training, it's SO much better to wait! This may sound crazy, but my son was potty trained in 3 days and I know it's because we waited until HE was ready and we had the time to devote to it. (I know you're all thinking "Yeah, right!", but it's the honest truth.)
I don't think he's ready, if he's not even two yet. Wait until he's able to tell you pee and poop and understand what those words mean.
Buy a potty and set it in your bathroom. Ask him if he wants to SIT on it. If he says yes, let him sit there as long as HE wants. If he says no, that's ok. Don't force him!
We did this with our son a couple months before he turned two and he had his potty for 6 months before we even THOUGHT about potty training. He went potty on it a couple times in those months, but that still didn't mean he was ready to potty train. I think it was more coincidence. The right place at the right time. :)
Good luck!
