It sounds like you really need some legal help. But I would suggest obtaining a consultation with an attorney. Your case is far too complex for a simple answer here on this forum. An attorney would need to see all paperwork pertaining to this case including everything filed by the childrens' father. You will need to consult an attorney in the town or county where the children are currently living as I would bet that the father obtained custody while your wife was in the hospital.
