I've had other kids, but none of them did this. The slightest hint of not getting his own way (which is most of the time because he is into everything and can reach all the inappropriate things belonging to his siblings) and he just screams. it is ear-splitting. Goodness knows what the neighbours must think goes on in this house.
Any tips?
Tried a bit of sign language. It has helped with 'down please' from his chair. His vocab is quite limited. I'm sure it is mostly frustration. Who wouldn't be frustrated in a world of forbidden treasures?
