Transitioning from bottle to sippy


My daughter is 13 months old and last month her pediatrician gave us the ok to use sippy cups and give her milk. She’s been doing great with milk. But she won’t use anything besides her bottles. I’ve tried several times to put the milk in a sippy cup and she won’t drink it. She uses the tommee tippee bottles. So I was wondering what’s the best way to transition into using sippy cups, and what’s the best kind of sippy cups that you guys recommend using? (She does use sippy cups for water, just not milk)
