Drinking milk out of a cup

Angelica • June 2016👶🏻💙

My son will be 2 in June and he’s still on a bottle. Part of me doesn’t mind but the other half really wants him on a cup. The problem is when he tastes the milk in the cup he makes this disgusted face and won’t touch the cup again. He’s so attached to his bottle but it’s just time .... what can I do?!
