I don't have a cleaner (anymore - had one once when I was earning laodsamoney) and I have % kids.
dd aged 14.5
ds's aged 12.5, 10, 3.5 and 18 months.
Older kids clean their own rooms and change their own linen.
dd does her own ironing. ds1 will be doing his very soon - I am working on him making him think he will be thought of as very grown-up if he does it!
The older 3 have a chore each every day. I do a general tidy up every evening and morning and every week or so I have a mad cleaning blitz.
dh does bugger all but has been feeling my wrath in the last few weeks since I started working 3 nights a week and has now cleaned the toilet for the first time ever in 5 years!
If I could afford it, I would most definitely pay for one. And a gardener (used to have one of those too). Not enough hours in the day to do it all myself.
