Newborn Quirks: What's Normal, What's Not

Newborns Are Strange by Adult Standards

Babies are born with an immature nervous system, and many of their normal behaviors look alarming to new parents. They make sounds you have never heard, move in ways that seem wrong, and do things that make no sense. Almost all of it is normal. This guide covers the most common newborn quirks, what they are, why they happen, and when you should actually call the doctor.

Eyes and Vision

A newborn's visual system is the least mature of all their senses at birth. Their eyes and brain are learning to work together, which causes many seemingly abnormal behaviors.

Breathing Sounds and Patterns

Newborns have tiny nasal passages and an immature respiratory system. Their breathing sounds alarming but is rarely dangerous.
