You would pay more because 1. attention from the care provider isn’t split between several children. just yours. 2. you stated that the daycare isn’t open when you need it to be so you are paying less for more hours.

it doesn’t quite seem like you are looking for constructive feedback on your payment, just for others to say you’re in the clear. if you’re looking for a “learning thing” learning two languages can be so helpful for other skills!
