The second day, where we had the cup, my tots already own it drunk (8Mo)! so if that does not say anything; D No, it does not say ... I find the cup totally practical, it looks kind pure, making it much safer when drinking. the mission was the second day there, super packed and everything without problems. I was stupid baby bottles even before I knew that there are also good reasons to (caries ect.) this mug is a super investment.
