I agree with most of the others.
I have a 15 month old charge. We mainly do free activities in the holidays, park, beach, swimming (nanny membership at local gym and she is a real water baby, already says 'splash splash' if I ask her what she wants to do!) friends for coffee/lunch and play, which can seem expensive when your nanny is hosting but we have a group of 7 of us so it is once every 7 weeks and inbetween there is a day a week when the nanny and children don't need feeding!
We have annual membership to three zoos locally, total cost of £90 per year but we go loads, (might not have all three memberships when we have to pay for charge too!) but we don't generally go in the summer holidays as they get far too busy. Although we went this week and had a wonderful day and charge still keeps talking about the zoo.
I don't have a kitty budget, as such, I pay for things and my boss pays me back at the end of the month, but apart from buying food, I always run things by my boss before spending her money! Even on craft stuff.
I will buy myself a coffee in a coffe shop from the kitty if we are there because of my charge, i.e., shopping for holiday bits yesterday, she needed feeding so I had coffee while I was feeding her, they don't tend to let you sit in a cafe if you don't buy anything! And if we went to the park with friends and we all had a drink/ice cream, I would pay from the kitty. However, if I was in town for my own reasons, picking up parcel from post office, etc and we stopped for a coffee, then I would pay for it myself.
I have sole use of a work car, on and off duty, my employer pays for the petrol.
If I go away for the weekend, I will replace my use, if I pop into town at the weekend, I don't. We have some friends with one child and so we will car share for longer journeys but obviously this isn't always possible.
My bosses are amazing, very kind, appreciative and generous, I would never take the piss! If they said, we'd rather you didn't go here or there and stayed closer to home, then I would understand, I would see if they would compromise to one activity further afield a week if charge and I enjoyed the class/liked the other children/carers, but ultimately, they are the boss and what they say goes.
hoping they don't see this and lay down the law!
