I know that what the Consumer Product Safety Commission said was that a child would have to keep a vinyl article in his or her mouth for greater than, I think, 95 minutes a day to approach any harm. What they then found in their mouthing study with children is that what children did indeed keep in their mouths for the longest time, their favourite, were the silicone pacifiers. So the behaviour studies didn't show that this is what children were doing. That just wasn't the behaviour.
We know also, at least in the U.S., from the Centers for Disease Control, that the level of phthalates used in toys is virtually non-detectable in the human population. I personally do not have a concern. There are other things I'd be worried about.
