I’m a nanny. I work 45-50 hours a week (on maternity leave currently)
The children were 2 and 5 when I started. I basically do everything they need, and apart from stack and unload the dishwasher with what we’ve used I don’t expect to do anything for the parent, the housekeeper does her washing etc.
I wash and iron and label all uniform, I purchase it too when needed
Put out all clothes and uniform for he t day and unpack/pack school things
Wash and iron all other clothes, purchase new when needed, put away/get out summer or winter clothes.
Wash all children’s sheets and do bed change weekly
Wash and change all children’s towels/flannels
Buy new toothbrushes, check medicine cabinet, replace anything if needed
Book haircuts, eye and dentist appointments
Plan all holiday activities I want to do with them- theatre, zoo etc
Keep a diary for play dates, clubs, activities, appointments
Batch cook children’s meals.
Sew and repair clothing, polish their shoes
Keep on top of their toys and take to charity shop ones that aren’t played with
Tidy all mess I’ve made with the children during the day
Pack for activities/trips/holidays
There’s loads more but that’s off the top of my head. But as I say I have more hours to fill! So you could look at the list and decide what is your priority and what she could reasonably fit in with her hours.
