Bottle formula/sippy milk transition

Taylor

My daughter is 11 months this week. Her pediatrician told us we could start whole milk last month but I don’t give her much and if I do I usually flavor it with formula so she’ll drink it all.

We have three sippys we’ve tried and she just can’t seem to get the hang of it after 3-4 months. Are there any good ones for bottle lovers?

Secondly, how and when do you transition completely off formula?
