Sarg,
I did it for my first little nephew.
He only stayed with me a few months but he was still a toddler at the time.
I know a few months do not compare to a life time but just wanted to assure you of a few things.
You're gonna bond with this little girl (specially since ya'll are females),
you're gonna grow to love children.
I know you seem kinda "iffy" right now but that's all gonna change
You'll do just fine....
You're gonna love this little girl as if she were your own daughter, and the love alone will insure your's and her's future.
By the way,
I'm no fortune teller but I speak from experience....
