Idk if its just me but I HATE when my SO nephew (2 years old) snatches toys away from our baby (11 months) I get their kids bug the way he snatches it from my son pisses me off. He does not know how to play/share! Seeing the little face my baby makes when he snatches it makes me want to just keep him in the room all day where he can play with toys privately.
