Automatic washing machines and tumble dryers have been around for a very long time. Not very recent inventions. I did managed to get through my first baby (born in 1969) still doing his washing by hand and the rest at the local launderette. But when second baby was born eleven months later we did purchase a washing machine (not plumbed in - often went walkabout when emptying causing many problems). Tumble dryer joined the household by 1973.
Central heating we also had from about that time - but double glazing not until the turn of the millenium, Could not believe the enormous difference that made in our old, Edwardian semi.
Our first microwave also arrived in the seventies, and a large chest freezer was obtained in the late sixties, as my hubbie was then working for caterers, although had great difficulty in finding places to stock it from - until Bejams came into being.
I have always preferred terry nappies which I used on my own six, as well as on numerous foster babies, to the disposable ones that all my g.children had.
I would say that central heating along with double even triple glazing are real wonders. No longer having frost on the inside of windows. Also the great materials from clothes are made making them all so easy to keep clean and not have to iron.
