I have an unusual problem that is creating tense situations at home. My 13y/o boy does not want to use his knife for eating. He bends his head to the dish to eat things like salad or pasta. He prefers to eat big chunks of meat to avoid cutting it and when he cuts meat, he holds the knife with his whole fist. To make it short, he eats like a savage or a 2 y/o.
The truth is that he seems to hate manual activities like writing, drawing. His writing especially is that of a 5 y/o, and writing characters... upwards!
My problem is also worsened by the fact that whenever I get mad at his behaviour, my wife gets upset at me, not at him!
Is this lack of ease usual? Can something be done about it?
