Yes that is a false but true statement I have seen 3 yr old who have understood that their momma is dead and that she ain't coming back I have seen em cry and say "No" but I have also seen some 3 yr old who don't understand that their momma ain't coming back and say "she's playing hide-in-go-seek" or don't understand when u say don't touch that it's hot but they touch it anyways
Hope this helps have a nice nite
