To anyone considering adoption, God bless you. We need many. many more adoptive parents.
If you adopt a special-needs chld from the public sector, there are often subsidies available that will continue until the child reaches majority. You wouldn't get them with a newborn unless s/he had handicaps but you can get them, say, with a relatively young sibling group.
