I have 3 school aged dc and I work part time term time. I admit I probably do have it easier in term time. Hence, I do 99.9% of work in house/childcare and all laundry in term time. DH is quite messy too.
However, he now has shut down for Christmas. We were away Xmas Eve and Xmas Day with his family. Before going I loaded dishwasher but it wasn't ready before we left. We returned Boxing Day morning when we unloaded car and I than drove with dc to visit my family. He didn't come as has a football season ticket.
Since than he has done nothing except play computer games. watch tv, build 1 toy for kids and maybe play for an hour or so with dc.
Dishwasher was still full when I returned late Boxing Day and his plate etc were in sink.
