Totally normally (even if not convenient for you :) My older son didn't start loving solids until 14 months. Only kid I know who refused to eat birthday cake or even frosting on his first birthday lol. So, it will happen soon, most likely, but I don't think you can push it. He'll be ready when he's ready.
For the sippy cups, I found the best way to get him used to those was to take the valve out so that when I tipped it up to his lips, the milk (freshly pumped warm breastmilk) would drip out. Once he realized that something he really like was in there, he gradually got the hand of sucking on it. And after he was one, I gradually shifted it from warm breastmilk to cool milk. But asking a baby to go from warm breastmilk from you to cold cow's milk in a sippy is a lot to ask. Take it in steps.
