Introduction
It is normal for a 2-month-old baby to wake up 1–3 times at night. The number of times a baby wakes during sleep varies and is not strictly fixed, as it depends on individual physical conditions and health status, leading to differences in how often they wake up at night. Additionally, nighttime awakenings in 2-month-old babies may be caused by wet or soiled diapers, but could also be related to underlying medical conditions.

It is normal for a two-month-old baby to wake up one to three times during the night. There is no fixed number of times a baby will wake while sleeping, as it varies depending on each baby's physical condition and individual constitution, leading to differences in how often they wake at night and variations in their sleep cycles.

Waking up once or twice at night is considered quite normal for a two-month-old infant. Most nighttime awakenings occur due to hunger caused by an immature gastrointestinal system; after feeding, the baby typically sleeps for about three to four hours. Close observation is necessary after the baby falls asleep to prevent or detect any discomfort. However, the frequency of waking up at night is not consistent across all babies. Some infants may experience frequent urination or discomfort in the buttocks area, which can cause them to cry during sleep. It is recommended to change the baby’s diaper promptly to ensure more restful sleep, which benefits healthy development.

In addition, nighttime awakenings in two-month-old babies may be caused by diapers, but could also indicate underlying medical conditions.
