new aupair due to arrive very shortly and want to avoid previous problems.I work shifts -combination of earlies afternoons and nights.DH works for same organisation but has no set shift pattern like I do-it varies wildly from day to day.In the past I have told aupairs that they work to my shift pattern and take no account of dh,as his hours v v v v unpredictable.What would happen is DH would come home unexpectedly whilst I was at work and ap would promptly clock off.DH very lovely but also very useless and I would come home at 2am to find dc asleep on sofa in full school uniform having had takeaway for tea (wrappers still on floor) to be woken at 7am in morning to wailing dd saying she didnt do her homework last night and ap couldnt help her would I get out of bed to help.Now I know I should tackle DH's extreme uselessness but to be fair he works v long hours and v difficult and stressful job-I have over the years accepted this 'facet' of an otherwise great relationship.This is why I employ an ap.Have told DH that with new ap he must take a step back and make sure ap carries on with given tasks,which he obvioulsy doesnt do himself.However down side to this is DC always very glad to see dad -want to,understandably,spend time with dad and not ap.Ideally would let tired dad do the fun stuff -take to swimming lesson for example,whislt ap does tedious jobs that dh cant/wont do,eg cook a decent tea.I know this seems like an no brainer-just tell the ap what is to happen, however experience tells me the subtleties of this arrangement would escape an ap.I realise probably no answer but perserverance with new rules, but wondered if anyone had had similar problem?
