A member asked:

Is my son having infantile spasms if he jerks when you bump the bed?

No: No. If your son is still an infant, then you're likely just seeing a very normal startle reflex. It is called a moro reflex in medicine when the infant outstretches their arms suddenly, and then retracts them, when they are startled.
