It's very telling…
I just searched "Can you make vinyl floors safe for your children" How can I make my vinyl floors safer for my children"
All I got in search returns is
"How to keep your vinyl floors from being damaged"
"How to keep your vinyl floors shiny"
More research is gonna be needed, my opinion
is that we'll end up finding out that it leaks chemicals in to the air ) if new) and from skin contact.
If you can't move yet, have a discussion with your wife about buying large area rugs. That way you can at least have most of the air covered for your lil one.
Good luck, many of us are very concerned about this!
