No, I'm not babbling baby talk. Tommee Tippee, the most popular brand of infant and toddler feeding products in Great Britian is now available here. I received only a Tommee Tippee Explora trainer cup to review, so I can't vouch for the rest of their extensive line of BPA and phthalate-free bottles, cups (available in five different stages), bibs, and tableware. My 3-year-old Jake is past sippy cups but he quickly volunteered to try this one. I love certain details like the rubberized bottom and stouter shape that keep it from too easily toppling over. It also has an attached lid that flips back and rests in a groove—ingenious! Can't tell you how many plastic spout covers I've lost, sometimes resorting to wrapping a bare spout in tin foil. The soft spout on this cup has a special valve designed by a physicist(!) so that "almost no force is required to drink" yet remains leak-proof. I observed Jake's cheeks to see if he was sucking any less (couldn't tell) but I agree the cup seems completely leak and spill-proof with not one drip escaping even when Jake shook it violently over his head.
A recurrent gripe I've had with toddler cups and bottles is that every crevice has to be meticulously scrubbed or else mildew sneaks in. So a concern I had with the Tommee Tippee cup is that the spout inside the lid is so narrow that I can't see into it or clean it out with a brush (see photo right). A dishwasher might clean it thoroughly but I'm part of the minority who handwashes everything. It makes me nervous to think that mildew is sprouting in areas I can't see so I'm hesitant to use it at all. Another more nitpicky gripe is that the lid doesn't always screw on so the spout is centered. The spout may end up over the handle, so you have to keep placing the lid on at different angles to get it centered...a time-consuming annoyance.
