Question
The baby has been playing happily for these days, but suddenly starts shaking their head, which somewhat resembles trembling before urination. The first rib on the lower left side is slightly outwardly bulging. Is the situation serious?
Answer
This condition may be caused by calcium deficiency leading to weakened bones and restlessness, resulting in the head shaking. If there are no other discomforts, it is recommended to supplement with calcium, such as through oral calcium gluconate or cod liver oil, and to get more sunlight to aid in calcium absorption. For a 10-month-old baby, introducing appropriate complementary foods can help with growth and development.
