Invest in some of those drawer dividers that separate drawers into a dozen little compartments. Clean and put away fifty percent of your decorations and knick knacks. Not only will this give your home a more modern, minimalist look, but you will get your dusting done in half the time. You help with her clutter disposal. Telling someone why you need a whole kitchen cupboard full of plastic containers can help you get them into that rubbish box.
Some people work on a one in-one out system.
For instance, if you buy a new sweater, toy for the children, etc. All the clutter didn't come into your home in one day and you won't get rid of it all in one day. Keep on sorting, dumping, tidying and labelling. Cut back on bringing new clutter home and it is a battle that can be won. You will have more time, a neat home and less stress as a reward for your efforts.
