Your baby just made a sound you've never heard a human make before. You froze, phone in hand, ready to Google or call the pediatrician. Take a breath -- most of what babies do in those first weeks sounds alarming and is completely normal.
Hiccups: The Diaphragm's Favorite Party Trick: Newborns hiccup a lot -- sometimes several times a day. It's just their diaphragm contracting as it develops. Hiccups are common both before and after birth, and they don't hurt your baby. To help: try burping your baby or offering a bit more feeding.
Sneezing: Not a Cold, Just Cleanup Duty: Babies are born with amniotic fluid in their nasal passages, and sneezing is how they clear it. Frequent sneezing without fever, congestion, or fussiness is typically just nasal housekeeping. Sneezing is a protective newborn reflex.
Grunting, Groaning, and Nighttime Noise: Babies grunt -- a lot, especially during sleep. Active sleep (a lighter sleep stage) comes with grunts, twitches, and little sounds. Grunting can also mean your baby is working on passing gas. Watch your baby's face and body more than the sound itself.
Gurgling and Rattling Breathing: A rattling or gurgling sound when breathing is usually just saliva pooling at the back of the throat -- babies don't know how to swallow it efficiently yet. As long as breathing isn't labored and your baby is feeding and acting normally, this is rarely concerning.
When to Actually Call: Breathing that looks like it takes effort (ribs showing, nostrils flaring), a fever in a baby under 3 months, thick colored mucus with congestion, any sound that suddenly changes or worries you.
