Prevention or constant cleaning?
Ds2 is 2 and there's a big gap between dcs so I'd forgotten the relentless drudgery of trying to keep on top of the detritus of a toddler's everyday life.
I did a deep clean of our (small) flat about a fortnight ago and the place was spotless. Now everything seems once again coated with sticky marks and the bloody crumbs 
I suspect part of it is differences in the way dh & I do things, we split childcare approx 50/50 and I don't think he's as hot on wiping hands as I am.
Urrrrgh. I gutted the car last night as it was going in for its MOT and you could have grown potatoes underneath ds2's carseat...
