I need to go searching for the info, but it seems Tupperware ran tests on their plastics awhile back when the xemoestrogen thing came up. The containers do not leach. And the ones labelled microwave safe will not leach in microwave if used according to directions. Here's what we do:
A tupperware tumbler cup with a the first years lid. I only use these lids because the valve actually gets clean. Cannot use the tupperware lids because ds takes oj and choc. rice milk to the couch
I even found a source for just the lids (so you don't have a bunch of cheap cups to feel guilty about). The Environments Pre-3 Child (preschool supply
) sells lids in sets of 12. We split among our house and the 2 grandmas. Their # is 1-800-EICHILD. Sorry can't remember how much they are.
I guess plactic is a ficture in our home. I always wanted to use the stainless steel and even some other "pretty" things. But ds's favorite thing is "hammer, hammer, hammer" with EVERYTHING. I swear I gave birth to BamBam! But gosh, he's cute. Maybe he will build me all kinds of beautiful furniture someday
