It happened to me today for the first time. Had to take DS1 to the doctor's surgery. He had a meltdown, he SO did not want to be there. He was lying on the floor, whimpering. I tried to pick him up and he screamed his head off. DS1 is three next month. The surgery was full. Everyone's eyes were on me. Smelly old ladies were tut-tuting and I know what they were thinking: 'she can't discipline her child'. I didn't know what to do. We got back in the car, DS1 was fine. I sat there for 15 minutes, sobbing.
He has regressed so quickly, it's scary. This would not have happened two weeks ago. Now he has lost almost all his speech and he just wants to play with things that have wheels. It's like I have lost my little boy. It's heartbreaking.
