We have no clue where difficult child is and have had no contact with him for two years now. We do know he is paying child support but truly have no idea where he is. Anyway - that's old news. For those grandparents who have chosen or been chosen to have custody of a bio-grandchild, what type of legal paperwork do you have? Our grandson is now 3.5 years old and is in a very dangerous situation - living with Mom, two sisters and new boyfriend who has hit our grandson in the face!!!! The other grandparents are livid as are we. We are trying to decide how we want to approach this. I would love to have grandson and would rearrange my schedule to make this happen. However, Mom's parents and us (we are baby's Dad's parents) want something legal. Mom has three children by three different guys - middle child is our grandchild. So....wise ladies of the board, what has worked for you?
