For those with small children who watch TV whilst they do chores but want them to watch less, the easiest way is to get them to help you. Yes it takes a bit longer but everyone's happy then also.
Using 'scotinoz' as an example. When mine were those ages I would do something like:
Dinner - 2 year old on chair next to me 'helping' by chopping easy stuff, mixing, watching, eating bits. 7 month old in highchair nearby watching, given a wooden spoon, sieve or similar to play with, plus something to eat from prep. ( mine love raw mushrooms for some reason!)
Laundry - 7 month old in Landry basket with washing playing with clean clothes, 2 year old helping to pair up socks or find his tshirts etc.
Cleaning - buy a mini Hoover (£20 hand held type thing). Entertains toddlers ages whilst you actually Hoover. Put towel on floor and add a washing up bowl with bubbles and water and let him 'clean' already clean spoons/ plastic. It's great for their amusement and an activity for them, and you can do actual kitchen etc at same time.
It mean if you don't mind them watching TV but would prefer less, you can use TV for when they are ill or when you are actually sitting down resting also
