It's no joke. Kids can get to this level of rage over the color of their cereal bowl, or twisty socks. Why? Usually it's because they have too many unspent emotions built up and when the socks twist the emotional limit is reached and the dam bursts.
The good news? As loving caregivers we can drain off the emotional pressure throughout the day. 30 second bursts of empathy for life's little upsets keep the emotion level manageable.
So make a bit of time here and there to connect and empathize!
