How long was your DC using the sippy cup before you put milk in it?

I bought DS the Nuby straw sippy cup (thank you to all that recommended it) and he loves it. I fill it with water in the morning and he plays with it throughout the day and drinks when he wants it. I tried to put milk in it in the morning bottle and he wont drink it. I am wondering how long did you let your DC feel comfortable before making the switch?

brendan was using the sippy cup for water for a few months before i started putting milk in it. i didn't start putting milk in it until he turned one and i switched from formula to milk.

Well Julia was BF for 11 months, so I gave her a sippy cup with Milk right after that (she never had a bottle or liked it).

My DD just turned 1 and I was putting water or a little formula in the sippy. Now she is almost all sippy's except her night bottle. She drinks milk out of the sippy for the last month.
