I live in Oklahoma. I have a child that is not a blood relative, but I have been taking care of him for quit some time, he lives in my home, I do have Power Of Attorney for a child. I take care of all his needs and expenses. I cloth him, feed him, I do everything for him as if he was my own. My question is, can I claim him as my child, or do I have to go another route. No one else will be claiming him on their taxes.
