Why does the baby cry and fuss every night at the same time?

Under normal circumstances, if a baby consistently cries every night, it may be due to factors such as hunger, environmental stimuli, deficiency of vitamin D or calcium, indigestion, or infantile colic. Parents should promptly take the child to a reputable medical facility to identify the underlying cause and receive targeted treatment. Specific analyses are as follows:

1. Hunger

Babies have relatively small stomach capacities and limited digestive capabilities, so they may need to feed frequently. If a baby does not consume enough food at night, hunger may lead to crying. In this case, parents are advised to feed the baby promptly, which will usually resolve the issue.

2. Environmental Stimuli

Babies are often more sensitive to changes and stimuli in their environment, such as light, noise, and temperature. Noises or bright lights at night may disturb the baby, causing discomfort and crying. Once the environment is improved, the baby's crying typically subsides.

3. Deficiency of Vitamin D or Calcium

Vitamin D and calcium are essential for a baby’s skeletal development. A deficiency in either nutrient may lead to skeletal developmental issues, causing pain or discomfort that affects sleep quality, manifesting as frequent night awakenings, excessive sweating, and crying. If necessary, under a doctor’s guidance, supplements such as vitamin AD drops, calcium gluconate oral solution, or calcium carbonate D3 granules may be administered.

4. Indigestion

A baby’s digestive system is not yet fully mature. Eating before bedtime or overfeeding can lead to indigestion, resulting in bloating, abdominal pain, and crying. Parents may gently massage the baby’s abdomen in circular motions to help relieve discomfort.

5. Infantile Colic

Due to immature digestive function, babies are prone to lactose intolerance, cow’s milk protein allergy, and indigestion, which may lead to infantile colic. This condition can cause symptoms such as abdominal pain, nausea, vomiting, and sweating, resulting in persistent crying. Under medical supervision, medications such as Xiangsha Pingwei Powder, lactulose oral solution, or live bacterial preparations like Bacillus subtilis bichimeric granules may be used for treatment.

In daily life, a light diet is recommended, and spicy or irritating foods such as chili peppers, Sichuan pepper, and garlic should be avoided.
