Patient's question:
Newborn at 23 days old, has been straining frequently in the past one or two weeks, with a flushed face. Hands strain, sometimes rubbing or scratching their own face, kicking, and making various sounds of effort with their mouth. This happens more often during the day; when picked up by an adult, it usually subsides, and they can fall asleep. Once put back to bed, if they wake up, they start straining again. During daytime naps, they generally eat and sleep without much fuss, not crying much. Recently, at night, they occasionally eat a few mouthfuls and then seem uncomfortable, wanting to cry but also wanting to eat, repeating this cycle. They are formula-fed, with regular bowel movements, twice a day, but with more curd-like particles and a sour odor, along with frequent passing of gas. Is it a calcium deficiency? I thought newborns under a month old rarely suffer from calcium deficiency?Doctor's answer:
The nervous system of a newborn baby is still under development, and the excitatory and inhibitory functions of the nerves are not yet well coordinated. They are easily excitable, and any slight external impact may lead to nervous system excitement, causing them to tremble, turn red, frown, and make humming sounds. During naps, they may experience startles and tremors again, with trembling in their limbs and body, and so on. This is a normal physiological phenomenon. As the baby grows older, the improvement in the development of the nervous system will naturally make this phenomenon disappear.
