Patient's question:
Before three months, the baby would take a nap every night from 7-8 PM and wake up once in the middle of the night at 3-4 AM. After drinking milk, they would sleep until 7 AM. However, about a week ago after getting the DTaP vaccine, they have started waking up once every night at 12-1 AM, and then waking up again every two hours after that. Sometimes they wake up every hour. The baby is exclusively breastfed. During the day, I often have a full milk supply, so the milk should be sufficient. But now the baby needs to be fed every two hours. She wakes up once at night and needs to be fed then. Is this due to insufficient milk or a reaction to the vaccine? Additionally, I have also started getting my period a week ago. How might this affect milk quality? Also, two days ago, I had a test, and the results showed no calcium deficiency. But the doctor said it might still be possible. So, what is wrong with the baby?Doctor's answer:
A four-month-old baby, who doesn't sleep soundly, may be experiencing early symptoms of vitamin D deficiency.Advice: This is an early symptom of vitamin D deficiency rickets. At this stage, the results of trace element calcium tests may be normal. It is recommended to further examine bone alkaline phosphatase and 25-hydroxyvitamin D3 to confirm the diagnosis and promptly give the child vitamin AD supplements. Also, ensure the child gets adequate sunlight exposure.
The above advice is for the question "A four-month-old baby doesn't sleep soundly at night." I hope it helps you. Wishing you good health!
