Hi Kyh,
I'm sorry if you've said this and I missed it, but is your wife hypothyroid? Is so, I recommend this blog: http://www.hypothyroidmom.com

I think you are doing the right thing re: car, as safety is the main thing for all concerned (just as Job said) ... I know this is hard, but I think you're doing a great job of staying neutral, validating and being a friend. All hallmarks of DB ... xoxoxo {{{{{hugs}}}}}

"Someone I loved once gave me
A box full of darkness.
It took me years to understand,
That this too, was a gift."
