Patient's question:
Now it has been more than six months. When I was a child, I was very well-behaved, but now I feel like I always cry at night. I don't know what's wrong, and I haven't slept soundly. Moreover, when I was four and a half months old, my neck couldn't stand up straight and I couldn't be held upright yet. What kind of assistance do you need: How can ordinary parents judge if their child is lacking in calcium?Doctor's answer:
1. Sweating; A lack of vitamin D can cause the baby to sweat excessively again, unrelated to room temperature or season, with more sweating occurring in the second half of the night after falling asleep, mostly on the head.2. Irritability; The baby may be fussy, uncooperative, prone to crying, uninterested in the surrounding environment, less active than usual, and have a strange temperament.
3. Restless deep sleep; The baby may have difficulty falling asleep, easily wake up, experience night terrors, wake up early, and cry uncontrollably after waking.
4. Delayed teething; Normal babies start teething between 4 to 8 months.
5. Weakened immune function; The baby is more prone to recurrent upper respiratory infections, pneumonia, nausea, vomiting, and other illnesses.
