Title: Very happy
Review: My son is almost 3 and still uses these cups. They keep milk and yogurt cold and are easy for him to hold and drink from. We began using these cups before his first birthday because they are easier for him to drink from unlike the other "spill proof" cups with the valve. This made for an easier transition from bottle to cup. There are no valves to get clogged and replace. They do leak a little bit when turned over, but in the big scheme of things, it's not a huge deal.
