After discovering the joy my child gets from drinking from a straw (it's the little things that keep you going!), I came across these Munchkin cups and decided to try them. I like the Munchkin products, and my child does, too. In this case, though, I would suggest waiting until your child is 2 years old or so to use the disposable straw cups. I'm fairly certain that pulling the straw out and throwing it on the floor over and over is as much fun as actually drinking from it. THe designs are cute and fun, and the cup is dishwasher and mocrowave safe, which is very convenient. It holds twelve ounces, so you won't need to refill it often. All of these are great attributes. However, it leaks more than the non-disposable version, and it really needs an extra peice on the straw to keep it in place.
