Their costs are the same albeit minus the food your dc would eat, so i wouldn't imagine you could stop paying the fees without giving notice and then registering and hoping there was a space and they hadn't filled your slot.
They can't afford to run with vacancies. No nursery can.
So you can quit the place completely, so they can re-fill it (and perhaps if you're on your uppers, refund you any payment in lieu of notice once they have a new family.
Otherwise, you might get a small reduction in respect of consumables your DC won't be consuming (maybe knocking off the cost of lunch ingredients) but don't expect much. I have known this happen when a child had a lengthy post-operative absence.
It does sound like she has left it open.. you can ask, she might say yes. If nurseries have lots of staff and they know well in advance, she may be able to tweak the rota of holidays, new starters etc to adjust her costs accordingly. I think it is worth broaching the subject.
It’ll be in your contact. If you don’t want to pay, you could withdraw hi from Nursery and take a gamble on his place being available when you get back. I don’t think she was leaving room for negotiation, I think she was being discrete.
If you give enough notice that she can look at staff rotas to see if she can manage with less staff eg/ say the ratio is 1:5 and there are sessions where your child is the 6th child meaning another staff member on shift she might be able to accommodate time off in lieu/holidays/training. She might be prepared to offset this saving on the fees for those sessions but I’d say this is entirely on her goodwill and she may not want to start a precedent because if other parents get a whiff of this they’ll be beating a path to her door
Of course you have to pay! The nursery will still have to pay staff, even if they are on holiday Are you going to ask your broadband supplier if you can have a month free as you won't be using it Or your gym?
Are you contacting your Mortgage/rent provider, tv licence, internet supplier etc and saying Im not using you so don't want to pay? Im sure they will say yes......
How do you feel that the nursery have less out going to pay for other than a few pounds for food (probably negligible as most of the cost is in the cook and the fuel. A blob of paint and a few sheets of paper saved are not going to save them anything. One child off doesn't even save staff as they need that member of staff for the other children under her ratio. You choose to go on holiday its part of the cost of going cant afford it don't go.
You will probably have to pay, as that is their policy, in my experience the negotiation usually comes in if you ask to have a few extra sessions when you are home, they may accommodate this as a goodwill gesture 🎃
