Question
How long should a four-month-old baby sleep each day to be considered appropriate? Do they need medical treatment, and how long until improvement can be seen after treatment?
Answer
According to the description, a four-month-old baby should sleep approximately 13 hours a day, including naps at 8 am, 11 am, and 3 pm, as well as nighttime sleep from 8 pm to 6 am the following day. Good sleep habits are crucial for an infant’s growth. During deep sleep, the baby’s brain stimulates the pituitary gland to secrete a large amount of growth hormone, which in turn promotes the growth of bones and soft tissue. If there are no abnormal signs in the baby’s sleep pattern, medical treatment is usually not necessary. However, if parents have concerns about their baby’s sleep situation, it is recommended to consult a professional doctor for more detailed guidance.
