We typically recommend changing your baby's diaper with each feeding, as well as in between feedings when Baby poops.
A good rule of thumb is to change your baby's diaper after each feeding and before and after each nap, or about every 2 hours during the day. If your baby is a newborn, you'll want to keep track of the number of wet and dirty diapers each day.
Do I need to change diaper at every feeding?
