My toddler uses straw sippy cups -- plastic cups with a two-part straw with a spillproof valve.  I'd really like to replace them with a non-plastic, or at least less-plastic option as they start to wear out and we lose pieces.  Does anybody know of any kid-sized containers with built-in straws?  Spillproof is nice, but it has to be a straw, not a sport top or anything else.

You might check out stainlesscups.com  I am ordering some stainless baby bottles and tumblers from them.  They have some different spout options.  One is called a sport top, but looks like a flip up straw and they do have silicone sippy tops.  May not be what you want… but worth a look!

Okay, some of the comments on that post were just silly.  Had to roll my eyes at people who were pro-bottle but anti-sippy cups.  My first kiddo absolutely refused everything except the breast until I got her to drink from a straw.  Sometimes mom doesn't get to decide!  She had several hungry days at daycare until I sent her off with breast milk in a toddler cup with built-in straw. 

Thanks for the ideas.  The ones at stainlesscups.com look like a good option for us.
