My baby's body twitches suddenly while sleeping and sometimes wakes up because of it. Are these startles normal, how can I reduce them?

Sudden twitches and startles during sleep are quite common in newborns and small babies. This is called the "Moro reflex" (startle reflex). As the baby falls asleep or is in light sleep, his arms suddenly open, then he closes them, and this movement can wake him.
This is part of normal nervous system maturation and usually decreases around 4-6 months.
To reduce startles from causing waking, you can try swaddling your baby. Having his arms close to his body prevents his arms from suddenly opening during a startle, which can help prevent waking. When it's time to stop swaddling (when he starts rolling), you can ease the transition by leaving one arm out to get used to it.
However, if twitches only happen when falling asleep and the baby's breathing is regular and color is normal, you don't need to worry. But if twitches suddenly become very frequent, you notice seizure-like repeated movements, or they continue when awake, I recommend consulting your pediatrician.
