What is the reason for a baby suddenly crying after falling asleep?

Patient's question:

No

Doctor's answer:

When the baby first falls asleep, it is still in the shallow sleep zone, which makes it more prone to being startled by external stimuli and experiencing sudden, jerky movements (spasms). If the parent gently pats the baby's shoulder or performs a similar action, the baby will usually continue to fall asleep. This is normal. As the baby grows older, the duration of deep sleep increases, and the quality of sleep improves.
