When I said enough and no more screentime. You got piss and beat your mummy' face with your both hand. You got angrier, you pull and ripping of your mummy hair.
Your mummy got upset and stern say it is NO MORE. You get even angrier that you run to your box full of toy and throw out all the toy from it. And you look at mummy like a mad face.
You are only 20 months old, not even 2 years (24 months old), why you so fierce and angry already?
You will disclipine and time out when you continue your bad tantrum just because you dont gey what you want.
