I don't scream at my kids.
They have a rota, just as we did .
You can't play with another thing until you put the first away. For bedtime, it's tidy up time - we all pitch in, then the routine of bath, milk, etc.
DH and I do a lot of the chores ourselves for now, but the kids pitch in as their abilities allow.
I see part of my role as a parent as enabling my children to look after themselves - that includes treating their things and consequently themselves, with respect.
I use Organised Mum, too .
Another big part of it is that DH and DD1 both have dyspraxia. DD1 has quite severe dyspraxia.
They both trip a lot, so we try to aim to keep the floors clear of clutter as much as possible to avoid accidents where possible.
