Not as trivial as what was reported by a single parent in The Age anyway ("Single parents eligible to adopt Filipino children", 5 Nov 08, The Age Online):
|the evidence showed that children adopted by single people fared just as well as children in two-parent households.|
Whereas there is considerable evidence otherwise:
|Gunilla Ringbäck Weitoft from Sweden's National Board for Health and Welfare in Stockholm conducted the largest study ever performed on how children are affected by single-parenting. This study, released January 25, 2003 in The Lancet was conducted over the course of a decade (during the 1990s), involving 65,085 children living with a single parent, and 921,257 living with two parents. |
I'm not saying that they should not be adopting. Having a loving single parent is much better than being a complete orphan. But having a loving father and a loving mother is still the ideal.
