My biggest concern if I ever have to adopt is, will I feel love for this child ? Yes I know that some parents can have postbirth depressions and then they dont feel connected to their child, but i think the chances of not loving the child is a lot higher if it's adopted. That special connection not being there, because it's "just" someone's child, that on paper, now is yours...
My sister had to go through a bonding program when she adopted. I'm not sure what all that entailed but she had to take off two weeks from work. No one was allowed to meet her daughter and then son until after those two weeks.
There are people who are not able to bond with adopted children. I heard about a woman who adopted a baby after having two. She didn't feel a real connection to that child like she did her two biological children and she found a new home for that child.
I would suggest meeting kids in foster homes and later, if you enjoyed spending time with them, take in a foster and start there. If you enjoyed fostering, then consider adoption.
I would recommend reading positive and negative stories of adoption experience just to see what you could possibly be getting into.
