This looks remarkably like a margarita glass. Since she is small, look for a plastic or lucite margarita glass, since it will be on a stem. Also, the stem might make it easier for her to hold onto the glass. You might also be able to use a parfait type glass, such as is used for ice cream sundaes. Both of these alternatives might work until the cup is actually available ir she is grown enough to use a regular cup.

a sippy cup they sell them is supermarkets have fun looking for one they are fun also ha ha ha?

welll they have sippy cups at your laocl sotre

I found this one online but it has not been produced yet and it is a great idea.

My little grand daugher is almost 4 yrs old, spills her milk each time they give her a glass of milk to dip into. she gets in bad all the time. It is just not fair for her not to have a stable cup that is just for dunking.
