How many diapers your child will need at daycare depends on the age of the child. Newborns or infants will need 9 or 10 diapers per day at daycare while kids 2 and 4 years old will only need 4 diapers per day.
Children tend to wet or dirty less diapers the older they get and keep their diapers dryer and cleaner longer than infants and newborns.
