If you just want ways of making life easier when there's only one adult at home.
I find it really hard to cook for 1 adult and a child, and found I was throwing away alot of vegetable etc, bulk cooking becomes your friend, get a slow cooker and a Morphy Richards soup maker.
Make chili, casseroles etc in the slow cooker, eat for your dinner that night and freeze the rest.
When you are coping the vegetables for the meal, do some extra and throw it in the soup maker, freeze that too.
The soup maker can also be used to make smoothies, so I always throw in any fruit that's been hanging around a while, Dd is much more likely to drink it in a smoothie or I freeze it to make smoothie lollys.
Make sure you are stocked up with medicines for both you and DC, especially if you haven't got anyone nearby that could get you some in the middle of the night.
Same goes for quick microwavable meals or some longlife milk or pasta in case the kids or you are ill.
I taught Dd to use the toaster and microwave at 8 although she's not allowed to use the kettle. Now I prepare breakfast during the week and she makes it at the weekend.
I keep an old duvet already made up so that should there be any sickness (we're past the stage of bed wetting) I can strip the bed quickly and throw the spare duvet on without messing around trying to make up the bed.
