What should I do if my 3-month-old baby flails their arms like they're startled while sleeping?

Patient's question:

Hello doctor! My baby is now 3 months old. Sometimes when sleeping, she lifts her hands up as if trying to grab something, looking very scared. Occasionally, she also does this a couple of times when awake. What could be the reason for this? Is it related to incomplete nervous system development? It has reduced significantly now, but before, when she was around 1 and a half months old, it was the most frequent!

Doctor's answer:

When you feel that the baby is startled, the closest person should pat and touch him more. Pay attention to calcium supplementation. Research shows that if the baby lacks calcium, they are more prone to being startled. My child was also like this when he was one month old—sleeping peacefully, suddenly opening his eyes, and raising both hands. Later, it gradually improved. Don’t worry. Creating a good sleep environment for the child is very important.
