A member asked:

My 4 month old has started startling (moro reflex) during light sleep. he did this 4x during his nap. is this normal? he just started rolling too...

A doctor has provided 1 answer

Yes: The moro reflex is present at birth & persists until about 3 months when fully awake or up to 6 months in mild sleep states. Loud noises, vibrations or movements can set this off. Kids often start to roll as early as 4 m.
