Make a list of all the work that needs done to care for the household
Put it on a weekly spreadsheet Monday - Sunday 8 am - 10 pm... fill in every cell slot to indicate where you are and what you are doing at that time...
If you want to be daring even add a column for each to the right showing the COST of the work too
And totalling hours of work at the end of each day of course...
Example
Monday 8 am | Make breakfast | $10 Food 9 am | Run laundry | $5 Load
...
6 pm | Make dinner | 15$ Food ------------------------------------ 10 hrs | total | $75 total
