You have the power to stop it dead in its tracks.
Point your finger at yourself. What is it about yourself that you are rejecting right now? What do you feel badly about? How are you not good enough?
Now, send some loving energy toward you. Accept and love yourself just as you are. You are perfect, right now, in this moment. Breathe and release.
I assure you, your kids' behavior is a reflection of how you feel about yourself. When you change YOU, all else changes too!
