hi all.. my 3 yo been able to control absolutely.. out of sudden he will cry and scream and reject whatever i gave him.. always when i bring him home and scream /cries in the bus.. no matter how nice i say he won't stop.. how to tackle? I'm feeling super stress with my on-going divorcing now and i don't know what is giving my son hard time..

There's nothing much you can do but to put up with it for now. This is something that almost every parent will go through. Be thick skinned and be mentally strong, this is only a passing phase. As for taking the bus, I totally understand that it's pretty difficult to handle. If I were you, I would also dread taking the bus. Is it possible for you to take cab or private hire for the time being? Or another method is to let him cry all he wants first, then when he stops, you can take the bus. I learnt from other parents here that this is the best way to handle the terrible 2 or terrible 3 stage - let him cry and vent his anger first, then when he finished and has cooled down, you can talk to him and continue with what you want to do.
