If she is mobile, she uses a straw cup - I like the Greensprouts kind. If she is sitting at the table, she uses a small glass, like a juice glass. If you're wondering how to start drinking from a cup, you can try shot glasses. They are still open but are smaller, which make them easier for small hands to pick up and mean that a spill is a much smaller volume. As an aside, we noticed "party shot glasses" at a package store the other day that were plastic and brightly colored and seemed like they would have been a good learning option if you can ignore how they were marketed.
