Is it unreasonable to expect the parent with a more stressful job (and possibly earns the most) to do their bit around the house and with the kids? I'm talking about both mums and dads who both work full time and same hours or similar hours, but whoever has the most stressful job or earns a lot more so takes on most of the expenditure.
I know winding down after a very hard day is important but at what point does your wind down time end and housework/kids become the next agenda in the evening if at all?
