What causes a baby to have trouble sleeping at night?

If a baby has trouble falling asleep at night, it could be due to improper feeding. For example, overfeeding before bedtime may cause discomfort such as bloating or abdominal pain, making it difficult for the baby to sleep. Additionally, excessive light or noise in the baby's sleeping environment can affect sleep quality and lead to difficulty falling asleep. Some babies may also frequently wake up at night due to calcium deficiency. Parents can help establish a regular sleep routine by encouraging more physical activity during the day and maintaining a calm atmosphere at night, gradually adjusting the baby's biological clock. Ensure the baby's room is quiet and dimly lit, with a soft and comfortable bed. Tools such as blackout curtains or white noise machines can help minimize external disturbances. Avoid feeding the baby too much or too little before bedtime, and do not give beverages containing caffeine. Offering a moderate amount of warm milk or warm water before bed may help the baby relax and prepare for sleep.
