Not read all of the thread however
However I work full time and still have to do the exact same number of domestic chores - I just have less time to do them
No you don't have the exact same number of domestic chores. Trust me on that one. For starters if you work full time then there are fewer hours where there are people in the house creating further chores.
I have been a SAHM and I now work full time. I was busy both ways Chores got done both ways However I have fewer chores now than I did when I was at home and still had children in Primary school.
These days our house is empty from 7 30 am until 4 pm most week days 2 1/2 days until 5 30 pm. (the 1/2 as one DD has a bi weekly thing so one week she is home at 3 30 the next not until 5 30) When I still had children in primary school it was empty from 8.45 to 3.30 each week day
Now with me working full time we have about 8 1/2 to 10 hours of unoccupied house.
Before when I was a SAHM w primary age children we had 6 hours 45 mins of unoccupied house..
Primary school children (and younger) make more mess than a older teenager does. teenagers help more than primary aged children do (or at least mine do)
Less washing to do as well as they get older.
Fewer things to be spread all over the place as they get older
Fewer items from school to sort out as they get older
So no you do not do the exact same thing as a SAHM and a SAHM does not do the exact same thing as a working full time mother does.
They are doing 2 different things. Its good both ways if you are happy with the way your life is.
