Hi all,
I'm the Nanny in question here (hello!) and I've started a new Live-Out position, which is novel for me as I'm used to being Live In. It's great, I love it.
I've started weaning with Little One and the parents have given me the login details for their Ocado, with the view that I add his and my food to the weekly shop - all fine.
The parents and I agree that it is good practice for the baby and I to eat meals together - which will mainly be breakfast and lunch. I will feed him his dinner but would like to eat dinner with my OH at home most nights, so dinner will be a solo event.
The parents have been really good, said straight from the start to eat what I want from the cupboards and order stuff from Ocado for myself as Little One is currently still on mush. Moving forward, I aim to eat the same stuff as the baby (again, I think its good practise).
ANYWAY, I'm really really conscious of not taking the piss with this, I'm a pretty anxious person so worry about taking food from the cupboards and am vaguely uncomfortable with ordering any expensive food on the weekly shop. I generally just eat a bit of salad foods at lunchtime at the moment, to keep the food shop down.
The food I buy for the baby is organic so a bit more expensive, and even just for him its working out to be £15ish extra a week and getting more and more.
How much does your Nanny (or you, if you are the Nanny) add to the weekly shop roughly?
The parents are not struggling for money, have never mentioned any negative about the food I buy to me, and their weekly shop is in the 3 figures already - though there never is a lot of food 
They don't seem to eat much themselves which makes me more conscious of not overordering.
