You sure can!...I adopted 3 boys in 2006, cared for them since 2003 after being abandoned by the mother (drug/alcohol addict).
I live in Florida. You will have to go through some "serious" background checking....schooling for several months also! Ur home will have to be "open" for social workers, HRS, etc. at any time! It all kept me "on my toes"!
It's hard work!...I'm 62! And my boys are now 17, 14 and 12. All doing very well!
I'm deaf and they are hearing....And they keep me young and running!!
Adopting a child is not a "spur of the moment thing" or "wishful thinking" for a child!...You must be willing to make a "difference" in the child's life. I'm a single adoptee parent! And raising teenagers is no piece of cake! It's hard!
Good luck if you decide to proceed in this endeavor!...It takes a "special" kind of person!...Hopefully, you are that one!
