I don't have two under 4 but do have four children, plus a stepson and am expecting baby number five - hopefully with number six soon afterwards.
I am very strict with my time at school , every minute is accounted for from 7am until 6pm. I have a marking timetable and will mark a set of books or batch of essays/exams a day to keep on tip of things.
One evening a week I leave at 4pm. That is written in stone and happens regardless. That evening I will not work between 4and 9pm.
Friday evening I finish at 6pm and then we go out as a family . That happens every week and is a highlight of the week .
Between getting home and 9 pm is family time, also set on stone.
I work from 9pm until about midnight most evenings. I work in my study where I can't be disturbed.
My weeks are full on but that means I mostly have weekends and holidays free. Again that is set in stone. If I can 't do my job in that time it is an unreasonable request. I became a teacher to have time with my family that is always more important than my job .
I do my housework in the morning before going to work . I then do housework as I do other things. For example cleaning kitchen while supervising homework . Cleaning bathrooms while supervising bathtime.
The children have chores every day .
My husband pulls his weight.
We shop online .
We have detailed schemes of work as a department, that means I am only ever tweaking lessons.
I do a lot of peer and self assessment .
