Query: Great for transitioning to a cup

This cup was great for making the transition while weaning. I already had a couple of other brands of cups but I could not get my then 12 month old to do more than sip from them. He needed to be adding several ounces of whole milk a day ... we tried this cup and the spout was a winner for him. The spout is soft and has a great shape, easy to suck from. The rounded handles make it easy for holding. He used the Born Free cup constantly for nearly two months, while getting used to other cups as well. However, the complaints about leaking and the handles spinning do occur over time. By teething on the spout it now leaks. Just one time of forgetting to put the valve in before tightening the lid down over the handle will cause pressure breaks on the neck of the handle, thus producing spinning. However I have yet to find a perfect cup and the Born Free was wonderful for us while making the transition!
