Great sippy cup
I love these for my 18 month old.  They are not completely spill-proof, but I haven't found any sippy cups that are.  These don't have too many parts, or places for mold to grow, and hold up great to a billion washings.  My son will only drink out of these Gerber cups now and has a lovely tantrum when I give him other cups, so they must be easier for him to use.<br />I now have about 6 of these in the rotation and have been really happy with them.
