Understanding Newborn Tremors: What's Normal and When to Seek Help

Newborn babies often display shaky or jerky movements, which are typically a normal part of their development as their nervous system matures. These movements, including jittering hands or jerky arms and legs, are usually harmless and resolve with time. However, it's crucial for parents to distinguish between these common infant movements and more serious symptoms that might indicate seizures, which require immediate medical attention. Factors like fine motor skill development, an immature nervous system, the Moro reflex, maternal caffeine intake, and even hunger can contribute to these tremors.
