I have 4 kids and 3 are at school full time this year. I also have 2 dogs so it's pretty full on.
I have a cleaner who comes every Tuesday. But that just scratches the surface. I do a lot of incidental cleaning during the week when I get a chance or something needs doing.
DH does the groceries on Saturday morning but I am able to get top ups during the week as there's a supermarket close to the girls' school. I'm shocking at meal planning (I actually can't be bothered). I may have to get better at it this year as my son's school is further away.
I do a lot of washing and ironing at night. Not perfect as I'd rather be doing nothing on the couch but this way I get to spend my free days whether my youngest free of jobs.
