My 1-year-old daughter is babysat by my sister in law. Her cousin is 21 months old and hits, sits, kicks, pinches and pulls hair. Her mom calls her a bully and says she does it to all little kids, but she is too young for discipline.
I have watched her do these things, there is nothing she is reacting to, she just walks by and hits. When we tell her we don't hit, her expression does not change, ever. She just walks by and casually hits and then continues on her way.
Has anyone dealt with this type of behavior?
