absolutely normal, when I am getting angry and tired, I think I seem likes a crazy dog and crazy lion and totally lost my temper and control, but anyway, try to learn relax and stay calm (I am still learning and not doing well enough), otherwise, our kid will learn to be the same bad manner as us which I can see now and don't want to see, if we want them to be happy, we must be happy, no way la, we are their mom ma, no one is born to be a good mom, we both add oil la
