Kids think the cups in this series are fun because they light up, but readers have reached out to me since our initial review about concerns with leaks, battery issues, safety concerns, and other sippy cup struggles. At the time of this original review, the main concern we had was with the light-up Wonder Cup, because it leaked on us. Since the kids hit the bottoms of the cups on the table in order to get the lights to flash, it makes the water kind of shoot upward and splash out. Read on for more details from the brand on how to get these concerns addressed.
Designed for ages 12mos +, this 10oz cup comes with one of those circular silicone tops where the kids sip the water from the sides of an anti-leak rim that’s also leak resistant. The strawless technology helps my three and five year olds feel like big kids without me actually having to break out the “big kid” cups that spill.
