Diapers today are incredibly absorbent. There are even nighttime varieties that do a great job of keeping your baby dry even if they wet themselves throughout the night. So, it’s not necessary to wake your baby to change a wet diaper unless they have soaked through their diaper. On the other hand, if you can see or smell that your baby has pooped during the night it is best to get them into a fresh diaper as soon as possible. Since the cool feeling of a regular wipe tends to be more stimulating, a great trick is to use wipe warmers at night to help keep your baby sleepy during diaper changes.
