I found these types of cups everywhere when I was baby shopping for my daughter. I never understood what the point of using one of these cups was until I bought one. The one I purchased bends so that you can get it really close to the babies head to rinse without having to worry about hurting the baby because you bumped them in the head with a cup. My daughter does not like water in her face anyway so this cup makes bath time faster and that makes for a happy baby. She is fine playing in the bath but the minute I try to put water on her head she is not going for that. This cup make things so much easier. Easier than using a glass cup because you do not have to worry about hitting the baby in the head. Easier to use because it holds more than a glass cup. Easy to wash and keep clean. If my daughter ends up playing with it I do not have to worry about her hurting her mouth if she tries to chew on the cup like I would if it were a glass cup.
