Depends on the age of the child
In the early days after birth, the baby's system is just starting to work so the number of diapers is low.
After about a week of age, most babies are making about 6 to 8 wet diapers per day. Many or most of those will contain stools. The stools transition from black color to bright yellow. As your baby gets older and starting taking solid foods, the frequency will decrease & color will change.
