I wouldn't worry Marigold, a scaled down version of that (i.e no children) doesn't work, even when it's what they expect!
I'll have to scan the two "Plans of work " for the housewife (one with live in maid, the other with daily help) in my Good House Keeping Home Encyclopaedia printed in 1952. I think in one of them you, having risen at 6.30 to sort out the boiler, you have half an hour to play with the child - a toddler.
