Anyone ditched bottles yet?

Sa

I'm soo nervous to ditch bottles! My guy turns 1 on the 13th and his appt is the 15th. I'm going to ask them for advice then. But he is def attached. This weekend I did mix some whole milk w his formula but he has still refused a sippy (i have tried 7 different kinds) just wondering if anyone ditched bottles yet and how it is going!
