Little and often, and lower your standards! lol
I confess, I'm not a domestic goddess. I should be upstairs tidying the bedroom which is currently a full on dumping ground but as DS3 is asleep in there at the moment it's not a possibility. I should also be doing the washing up, but tbh, I'm comfy! lol
Every day I try to do the basics so kitchen tops, at least some of the dishes, and a load of washing. Push the vacuum around the downstairs. Tidy the living room of all rubbish and plates etc and stack toys neatly at the end of the day.
Add in to that the cooking and general maintenance of the children that's the day full already.
Usually I can put DS3 down for a nap 2x a day, so I use that time to try to do a 'job' so something like dishes, folding washing, hanging it out to dry, clean the bathroom or sorting out the bins. When he was younger and napped more I had a vibrating rocking chair that he would sit in and I would move it from room to room as I moved.
Hubby has the fish tank, most of the garden duties (although I do these if he's away/busy) and he fetches and carries out of the loft.
I then have a set day when I change bedding or vacuum the whole house. These are normally days where I know I have no-where else to be so I can do them quite early on then spend the rest of the day catching up the rest of the jobs. Either that or they're done on days when hubby is home to watch the kids and i run around like the proverbial blue-arsed fly lol.
I try to spend no more than 1 hour a day doing general house-keeping tasks. I also confess that if I have a couple of 'off' days if I'm ill or if we're busy and in and out a lot, the housework does get forgotten, but it's still there the nest day so I just deal with it then.
