There is a large number of kids that don't get the terrible twos until later on. Do you think it is worse when the kids get the terrible twos later than two?
I do think it would be more frustrating the older the child is. I do not have children, but I have seen many other children with cries and screams of "NO" for everything. I have also witness the tantrums. I can't imagine how annoying and infuriating this would be if your child were lets say 17.
