Munchkin Bite Guard Sippy Cup

My oldest would bite through all other sippy cup tops, so I figured I'd try these out, and low and behold, he was able to enjoy the sippy cup and not end up biting the tops off!

These really seem to be holding up!

I don't know about anyone else's but my kids bite through their sippy cups. Now my last little has been doing it, and I finally found a soft top but now they've added a bite proof ring guard around the spout. Makes it so much more durable she hasn't even made a tooth mark in it yet. I would recommend to anyone whose littles might do the same!
