Review on Customizable 9Oz Pink Insulated Sippy Cup - Munchkin Miracle 360 + Stickers! by Amanda Hall

The Munchkin Miracle 360 cups are my go-to cup for my toddler. After lots of leg work, I believe these cups are the closest to leak proof that you're going to get. I find they only leak if dropped on the floor forcefully. Otherwise you can hang them upside down and they don't leak. My toddler had no trouble learning how to drink out of these at around 1 year of age. She doesn't chew them and they don't get damaged the way sippy cups with a spout can. She loves them! And the fact that this one is insulated is perfect for keeping milk colder longer or ice from melting as fast. Great for traveling!
