I agree.  What's your favorite part about child rearing?
Parenting refers to the intricacies of raising a child,biological or not
It certainly does and can be an enjoyable experience for all inolved!  Do you have any kids?
Have you raised a child before?
No I sure haven't.  I am an uncle to 3 children though.  Me and my nephew play basketball and go fishing a lot.
There are cases wheremany cases, orphaned or abandoned children receive parental care from non-parent blood relations.
