I personally do not work past 5pm anymore for this very reason ~ whole point of working from home was to create work life balance and wanting to be able to get to evening extra curricular activities and so forth.

When I was working until 5:30 clients were aware that I would start prepping dinner and any children here that late would be engaged in quiet table activities in the kitchen ... dinner was ready to be 'served' the minute the last child left.

However if I was working until 6:30 that is very late for both your family and the child to be waiting for dinner ~ would they consider paying extra and you just feed the child with your family???
