Query: Good idea bad product

I got these cups for my 15 mo old son. I thought that they would be great, a nice cup to take with us when we go out that I would not mind if we lost. I bought two packs and opened them right up, wash them, and then handed one to my son while he was sitting at the table. Not even two seconds later he had pulled the cap off and dumped the cup. This would be a great idea if the lids screwed on like the other sippy cups. The lids are really easy to take off. I would not recommend this cup to anyone unless you want a cup that your kids can open and you want to sit right next to them when ever they use this cup. Me I would just rather give him a regular cup he can not make any more of a mess. I love the other take and toss items and an really disappointed in this one.
