I would say before you try and get started.
Start reading,
From what I have seen it's best to know this stuff inside and out before you even start the procces.
If you like I can recomend some web sites I have found with alot of helpful info on them.
I havnt adopted a child yet but I'm reading all the info and finding what i can for when the time comes that I can start it all
I'm ready for anything that comes my way.
Anyways if ya want site address contact me and i'll send them your way.
Thanks
take care and may God bless.
