Droolicious has written about the Foogo Sippy Cup and Straw Bottle by Thermos before (read that post here), but I have to toot their horn since I just purchased one of each and I'm in love. It's wonderful knowing you can fill the sippy cup with milk and not have to worry about refrigerating it up to six hours. I hate throwing away milk, but I also hate worrying that I've left it out too long.
I read the comments from Heather's first post on the Foogo Sippy Cup and someone had an issue with it leaking. There is a trick to keep the sippy cup from leaking. Simply make sure the spout is dry when you put it together with the valve. (The entire top part of the sippy cup.)
Both the sippy cup and straw bottle are BPA free and are made from unbreakable stainless steel. Available in blue and yellow and pink and purple. And, boy, they sure look cool.
Find the Foogo Sippy Cup for $15 and the Foogo Straw Bottle for $15 at The Soft Landing.
