It is a huge decision a couple must make when they decide if they want to adopt a child. They will first have to look at all the pros and cons and then re-look it again.
One thing is certain, there is no turning back.
There should not be any difference between a biological child and an adopted one.
My son adopted a little boy and he treats him exactly like he treats his other children.

Good luck with the contest, and thanks for the invite!
