If you were at a playgroup, and a mother kept getting physical with a child that wasn't hers, what would you do?
The mother in question keeps going up to a particular toddler and snatching toys off the child to give to her own child. More recently she seems to take toys off the child that her own child doesn't even want. She prises the child's hand open and it makes the child cry and writhe to get away from her. It looks painful. She's not hitting or shouting at the kid, but this behaviour makes me really uncomfortable. What would you do if this was your child, or a child you knew?
