I went back when DS was 11 month and he never took a bottle either. I just started giving him milk or water in a sippy with meals, so he could get used to it, and when I went back I fed him only morning and night as you plan to do. It took a few days for the flow to adjust, and he weaned himself shortly thereafter (about 13 months.) He began to enthusiastically take a bottle as well, and then I couldn't get him OFF it at bedtime until he was almost 3! LO's are pretty adaptable, I am sure it will work out fine.
