Adopting?

Riley
So my Dh really wants to adopt he was adopted as a child and wants to give anothe kid what his adoptive parents gave to him. 
We've been trying to conceive for 6 months and both able to have kids. 
So I would love to adopt just would feel guilty especially cause we are able to have kids.
What do you guys think is it ok for people who can conceive to adopt?
