Taking away bottle. Help!

Emma

My little one is 11 months he was exclusively Brestfed for 6 months till he flat out refused it. So then we switched to bottles and now I am thinking of trying to take it away and change to a sippy cup only thing is he can't figure out how to tip up the cup to get milk. So my question is could I give him the milk in a straw cup instead of a sippy cup? And slowly swap bottles for a straw cup.
