Babies startling during sleep is very common and usually nothing to worry about. This is called the Moro reflex (startle reflex). In newborns and early months, the brain isn't fully mature yet, so during sleep the nervous system sends out signals on its own. This makes baby suddenly throw out their arms and legs, then pull them back in. Usually fades around 4-6 months. If baby doesn't wake right up and stays calm, this is completely normal. If baby wakes up startled and cries, you can gently swaddle them (in a way your doctor recommends that supports hip development) or hold them lightly to calm down. If startles are very frequent, last a long time, or baby shows other signs (seizure-like movements, turning blue, trembling while awake), ask your pediatrician for an evaluation.
