Unfortunately, it is not possible to pause a recurring payment for the nursery benefit. If you have set one up and, for any reason, need a specific month's payment to be skipped, you will need to cancel it before that month.

To continue with the payment for the remaining months, you will need to create a new request through the app. Please note that you can choose the start and end month of the payment, allowing you to adapt it to your needs.
