You are paid $10/hour for each child, if they are booked by separate families. If a parent books more than one child with the same provider during the same slot, the second child is paid out at $8/hour. This discount ensures it doesn’t break the bank for the parent, while compensating you for the extra work.
If only one child books a single hour with you, you will be paid $15 for that booking. However, this is only in the event you have more than one slot and more than a single hour open for a parent to book.
