Our almost three year old daughter can be very defiant and disrespectful. When she wants something, she wants it right away. She will ask repeatedly for something even when we tell her no. She is always trying to grab things away from her one year old brother or knock him over. She is always telling us what to do. It seems as though she is always ahead of me and in the moment I don’t know what to do other than tell her no. It feels like there are a lot of problems with her behavior but I don’t know where to start, please help!
