Diaphragm Development

Fetal Hiccups

Baby gets hiccups in the womb as the diaphragm matures, feeling like rhythmic movements.

📅

Development Timeline

Weeks 16-40

Overview

Fetal hiccups are common and completely normal. They feel like rhythmic, jerking movements that occur at regular intervals - quite different from kicks. Baby hiccups as their diaphragm muscle develops and practices contractions.

Hiccups usually begin in the second trimester and become more noticeable in the third. They can last a few minutes to over 30 minutes. Some babies hiccup multiple times daily, others rarely.

Hiccups are believed to be part of neurological development and practicing breathing. They're a sign of a healthy, developing nervous system. There's no way to stop them, and they don't bother baby.
