The parents should take care of their children so they could easily build bonds together wether good or bad situation. as uncle to the children, you can do well to assist the parents financially by passing the children the school fees when the need arises, send them money once once for upkeep, and a whole lot more. But outrightly taking the kids away from their parents is what I wouldn't endorse, nobody is in a better place to take care of a child than his parents.
