I'm self employed here and its a busy busy farm with other business so long hours and stress.
I agree with whats already said but my tumble dryer was a godsend. You iron very little, the clothes are softer and you can sort out the pants, socks into seperate piles.
As for a cleaner, again, agree if you can find someone who is reliable and cleans properly then its a help but my place is dusty and grubby after 2 days of a cleaner coming over so realistically I would need her twice a week but cant justify or afford that.
Dont bath the kids everynight, just isnt necessary when young, it seems a waste of hot water and time. Once a week plus a shower at the swimming pool after lessons. My kids dont smell or look grubby - use a flannel instead.
Big freezer, buy meat in bulk ie meat box, chickens etc. Buy bread in large amounts and freeze. Batch cook as much as possible.
Wall calender in kitchen, magnets notes on fridge.
Think plenty of mums are lucky if they have the luxury of weekends together with the OH. If so then it should be easy to find hours to catch up while OH takes the kids out. Use grandparents more (I do find mine are very selfish with helping out).
Training the kids is great but that depends on their age mine arnt old enough yet.
