DD2 is a little bruiser.
She loves pulling people's hair - she's always grabbing mine and her sisters and the more you tell her no the more she cackles and thinks it's funny.
She's also quite keen on headbutting people.
She is so strong and has such a grip. She'll grab the dog by the collar and drag the poor dog around (obviously I separate them as soon as this happens but it's just incredible how strong her grip on the collar is).
Is theere anything I can do, or will she grow out of it?
