We came back for this after purchasing another just like it, earlier in our grandchild's life. It has held up the best of any toddler sippy cup/bottle we own. Thanks to the invention of food pouches, even young toddlers get the hang of sipping out of straws at an early age. Our granddaughter has been using these in our house since she was a year old or earlier for water or juice. I wish they'd stock more different designs. I put them in the top rack of a dishwasher, straw and all, and they come out beautifully.
