Swiss aunt to the rescue. Lucas now has a funky new Sigg bottle. He loves it because it is so darn cute. I wasn't sure he'd be able to drink form it, since it has a sport bottle type of sprout, but he just went for it (probably cause he was so thirsty from waiting).
I looked into other non plastic sippy cup options. I know Born Free is BPA free, but I'm iffy about all plastics now and would rather avoid them altogether if possible. Klean Kanteen and Safe Sippy are less cute, bulkier options. And just wait, in 09 cuteness will be proven to reduce risk of cancer in laboratory rats. Foogo, besides being a a funny word, has adorable stainless steel sippy cups with handles (Marcia Cross's girls have them.) These I like too. But we're Sigg people all the way.
