With these snack cups, Darby can easily reach in and grab her snack, with out being able to dump it all out at once! Also, she pulls out just what she eats so there's no mess (but I'm sure it's possible!?) and whatever is still in the cup can easily be saved for later!
I usually bring one filled up with a snack for Darby whenever I need to run errands. It's easy for her to hold on to (she usually holds one of the handles, although she isn't in the pictures!) and best of all it's self-serve so I have both my hands free!
