I had a mtg with dc when we said goodbye to our last Au Pair (2 yrs ago) that we were going to save the £ spent on her by doing her work ourselves then using the savings to do fun family things instead (and pay the mortgage)(and stop me getting frazzled and stop dh continually complaining about the mess).
Each dc age 5-10 (4 in total) then told me what jobs they could do: ds1- cleaning counters after every meal dd1- putting things away dd2- vacuuming kitchen ds2- tidying playroom.
DH does bins, dishwasher, mowing etc.
Me: cooking, cleaning, laundry, gardening etc
I can say after consistently doing their jobs they all do it well and I no longer have to ask.
I don't feel frazzled, dc are more helpful and appreciative in general as a result.
