Does parental Leave work that way. My stepchild has lived with me for 10 years and still lives with me now. Her Mother recently passed away and at this time I have no Legal Custody. I am trying to get her Biological father to sign custody to me. If he does sign, would I be entitled to Parental Leave? I'm not doing this just for parental leave mind you. I just want to know if it would be an option. Being a single parent is difficult.. being a single parent in the military seems impossible. I just thought maybe this could give me some time to try and work things out so I don't have to VR.
