I second the idea of taking a day out to blitz the house. Once it's clean and organised it's easy to keep clean.

Personally, I'm a neat freak and have to keep things tidy, other wise I feel out of control (actually I could be a little OCD about it all, or at least DH thinks I am LOL). But what works for me is doing everything as I go. Get out of bed, make the bed. Make breakfast, clean up breakfast. Get a load of washing out of the dryer, fold the washing. Put DS to bed, clean up the toys etc. It means that you do have quite a few 5 minute tasks here and there, but that's all it is, 5 mins at a time. You don't get to the end of the day and have a huge list of housework to do.

Then, I would take your DP's advice and draw up a cleaning roster. But, I would make sure that the tasks are evenly shared between the TWO of you. Maybe even have rotating weeks so one of you isn't always stuck cleaning the bathroom.

HTH
That sounds really great and something i/we can easily do! Thanks heaps. I used to be the same before DD and then got struck down with PND so lost all motivation to do anything i was lucky if i could function properly.
