Re: bottle or sippy cup?
I would probably do the bottle too. I'm not sure how to teach babies how to drink out of sippy cups. My older daughter still hasn't figured those out - and she's 2.5. She likes the straw cups, although she mostly drinks from an open cup...
I gave my 6 month old one of the straw cups to play with the other day and she actually drank water out of it!! So, it's probably not that hard to teach them how to use those.
