I thought about making an attempt to switch to all sippy cups and stop the bottles since she does so well drinking from cups and straws. The only issue is it runs down the front of her. Which with water I don't mind but formula/milk is a little messier. I've tried the 360 cups, straw cups and hard spout sippy cups from tommee tippee and I guess they come out to fast. Any suggestions don't want to spend money trying out every cup but will if we have to.
