It is common to worry about disturbing your baby's sleep during a diaper change, but leaving a wet diaper can lead to leaks and discomfort. Many parents recommend using a very dim nightlight—ideally red-toned—to minimize stimulation, and performing the change during a scheduled feeding session so the baby remains drowsy. To prevent leaks, try sizing up your diaper for the night or switching to a dedicated 'all-night' brand designed for higher absorbency.
