Now I am all for asking my children to discuss their feelings and share their opinions. I do believe that it is important. However, if my child is flailing on the ground in the middle of a parking lot the last thing I am going to do is ask them about their feelings. At that moment in time my child is behaving poorly and I will NOT tolerate them laying on the ground (which by the way isn’t all that safe in a parking lot!!) because they are unhappy.
If you are unhappy, fine – but you can express that when safely in the car, or outside of the store. You do not get to act like a butt and throw yourself around to get your way and expect me to just sit back and watch it happen. Especially in a parking lot where you could get run over by another vehicle.
