Why won't a ten-month-old baby sleep during the day?

A 10-month-old baby not sleeping during the day may be due to normal physiological reasons or pathological conditions such as vitamin deficiency or pediatric gastroenteritis. It is recommended to immediately identify the cause and consult a doctor to determine appropriate treatment measures. The specific analysis is as follows:

1. Physiological Causes

Excessive indoor lighting, loud noise, and high room temperature during daytime may interfere with the baby's ability to sleep. If there are no other abnormal symptoms, special treatment is usually unnecessary; simply creating a comfortable living environment for the baby is sufficient.

2. Pathological Causes

1) Vitamin Deficiency
Due to rapid growth, babies may develop vitamin D deficiency, leading to increased nervous system excitability, excessive sweating, irritability, and disrupted sleep quality. In such cases, consult a doctor about using supplements such as vitamin D2 soft capsules, vitamin AD drops, or calcium carbonate D3 granules, along with proper dietary adjustments.

2) Pediatric Gastroenteritis
Infections caused by viruses, bacteria, or fungi can impair intestinal motility and function, resulting in symptoms such as diarrhea, vomiting, and fever, which may disrupt daytime sleep. Severe cases may involve crying and restlessness. For mild cases, actively correct fluid and electrolyte imbalances. For more severe cases, consult a doctor about medications such as lactase tablets, Bifidobacterium live powder, or Bacillus subtilis and bifidobacterium live granules.

In addition, conditions such as intestinal colic, infantile seizures, or intussusception could also be potential causes. It is recommended to take preventive measures throughout the baby’s development and seek prompt medical attention if any abnormalities occur.
