I hesitate to feature products that boast to prevent things that make parents paranoid, but this one really got me thinking.  Now I will admit that both my kids were sippy cup fanatics and said cups were made from plastic.  According to extensive studies, I was slowly poisoning my kids, which really, is the only way to do it.

With Klean Kanteen, you don't have the risk of harmful chemicals being served up with your spawn's 100% organic, range free, all-natural, granola-eating, tree-hugging, sandal-wearing, sugar/fat/salt/preservative-free, glacial spring dog drink on the rocks.

12 ounce sippy is $17.95 or 2 for $33.90.  Had I the chance to do it over again, I would have adopted 3 year olds and avoided the whole sippy cup debate, or you know, bought these.
