For 12 years I have been a SAHM, three children aged 12,9 and 7, youngest has special needs. Dh works full time and is also now doing an MBA. From September I will go back to secondary teaching, .8 timetable which means one morning, two afternoons and one full day off per fortnight, but most likely will need to do planning and marking then and in evenings and possibly at weekend. How should domestic tasks, which so far have largely been done by me, divided up now? If a cleaner was hired, is there an obvious answer who should pay for it?
