If you’ve already confirmed a sitter but you’re both happy to change the dates then you’ll need to unconfirm the sitter first.
Just select ‘Unconfirm’ in your messages with the sitter. There will be an option to unconfirm the sitter above the conversation thread.
Once you've unconfirmed the sitter, you will need to go to your dashboard and click on the 'Manage Dates' option. From there, select the date range you wish to change. Make the changes you need to then select ‘Save changes’. You’ll be asked to confirm this change. You can then ‘Close’ the date manager.
Then you can reconfirm the sitter. Just select ‘Confirm’ on your dashboard, or alternatively you can do this back in your messages with the sitter.
