Lately I feel I've been shouting at DCs, particularly our eldest, far too much. They are at the age where they are fighting over toys and games (eldest is at school, youngest is preschool) and answering back, and I keep losing my temper and shouting for things which I later think were utterly trivial (like spilling a glass of milk or fighting over a toy). Work has been very demanding and I feel constantly tired, but I'm worried that this will affect their behaviour and how they see me.
They aren't badly behaved as a rule, and are lovely, eccentric little folk, but I just keep losing the plot when they act up. I apologise to them for shouting but don't know if that has any effect.
Any advice?
