Help - I share the school run with my friend. Her son regularly throws a tantrum. Luckily my son rarely behaves in this way and if he does I show zero tolerance - I am firm, make him understand that his behaviour is unacceptable, and then ignore it. Can I treat my friend's son in the same way? His behaviour is making the journey to school miserable as if he doesn't get his own way, he screams. My friend knows he has behavioural problems but is very gentle with him and just seems baffled.
Advice very gratefully accepted!
