S.O.
I just wanted to say that the stage one cups are bad for you kids teeth. Biting down on the hard top is bad for the growth of teeth. I have a better suggestion. Since you daughter knows the cup concept there is a cup by playtex calls the Drink Up Cup. It looks a regular cup but has a spill proof top on it to prevent spills. There is also another cup called the Cool Sipster. It is a spill proof tumbler (looks like moms travel cup but spill proof.)The magic trainer is also an excellent chioice.
