My son's favorite cup

The baby's first straw cup has a weight on the bottom of the straw which allows it to move with your baby/toddler. My son loves this cup since he doesn't have to worry about moving it a certain way just to drink. We have other cups like this, but this one has been my favorite as well because it has yet to leak. Like most Dr brown bottles the straw has a few more steps in cleaning than other brands. The lid does get annoying, but it pops off/on easily.
