You really should read this article found on:-
http://www.childjustice.org/docs/bonthuys2005.pdf
I know it refers to the South African constitution, but it is extremely well reasoned, I believe, and has important things to say about matters you all say are important to you like equal or shared parenting (- not joint legal custody - got that distinction now!!).
I hope you give it some of your time and then assist me in making my mind up about it (I think I'm wholly in support of the authors position, but want to be sure I'm not being mislead).
Thanks in anticipation.
