Title: Best Sippy Cups
Review: This is the best sippy cup I've found, and I've gone through quite a few. What a waste of money with all the other cups I've been through; for the same amount of $$ I could've gotten these plus change left over! My baby wasn't able to suck out of all the "leak proof" sippy cups (and I've bought at least 3-4 others) but these he'll happily use. Plus, it's a two for one because you can use it as a regular cup afterwards. And there are only two parts to wash!One thing you have to beware of though -- DO NOT BOIL these per the instructions! I did, and it warped the lids so badly there was no way it would fit back onto the cups; so minus one star. Since they were cheap I just got more.
