Review on Tommee Tippee 'Sippee' Toddler Sippy Cup: Spill-Proof, BPA-Free – 9+ Months (3 Count Pack Of 1) by Randall Kelley

So first of all, we have bought several different cups to help my son transition his milk drinking from a bottle and then to a soft-spout sippy. However, we were struggling to get him off the soft-mouth sippy until this cup. Finally! It's the only cup he'll drink milk from for some reason.Anyway - I see a lot of people complaining about leaks. It only leaks if you don't reassemble the rubber piece properly and if you don't twist the top on properly. Since this is the case with all sippy cups and twist on tops, I'm not sure what people are so upset about. Frankly, once we understood how to properly put the rubber/plastic pieces back together it's been amazing. These things don't leak at all and my husband has tested them to make sure liquid comes through -- it does.These are totally worth the money and we already want more since (not shocking) we lost one of the rubber pieces.ahhh life with toddlers.
