2. Unpredictable Movements Are Normal
Newborns often make jerky or twitchy movements that can seem strange or alarming, but these actions are a sign of a developing nervous system. The Moro reflex, also known as the startle reflex, causes babies to suddenly throw out their arms and legs in response to loud noises or sudden movements. This reflex usually disappears by 2 to 4 months of age. You might also observe muscle twitches or shaky limbs which are normal and reflect the baby’s growing muscle control. However, if the twitching is continuous or accompanied by other worrying symptoms, consult your pediatrician.
