I’m pregnant with my new husband’s baby. My ex and I share two children and split custody. I am still very close with my ex’s father, after all, he was my father in law for 7 years. He is very interested in being a part of my baby’s life. He’s offered to babysit and wants to buy us a crib. He is my boys’ grandpa and I’d really like to stay in his life. Would this be super weird?
