My mother went off with this boyfriend of hers and my father was left alone with them and he has been very neglectful of them. One of my sisters has Cystic Fibrosis and he's been smoking around her and he hasn't been attending to her medical care right. He just hasn't been paying much attention to their needs at all because he's been so wraped up in his own issues. He even gets mad and has hit them. I took them over to my place for now, but is it possible for me to keep them permanently? They're 6 and 15. I'm 25. I know how to care for them. We live in New York, I'm a nurse. They want to be with me.
