It does exist! A sippy cup that doesn't leak!:)

I just wanted to do a quick update on the leaky sippy cup issue. I have tried literally all sippy cups made to man (ok maybe not, but close). Finally, I tried the Gerber graduate nuk sippy cup and no leaks!! The valves are plastic and easy to clean with no mildewy stuff that gets stuck in the nooks and crannys of some of the other brands. They are not the cutest or most unique looking cups, but they are the only ones I buy now. I am done cleaning spots from leaking drinks on the couch, carpet and carseat! Hope this helps anyone who may have been dealing with the leaky sippy cup issue:)
