5 Wild Things Your Baby Does in the Womb

The short answer: Your baby is busy in there. Long before birth, babies swallow and taste the flavours of what you eat, practise breathing movements, get hiccups, experience dream sleep, and learn the sound of your voice — which is why newborns turn toward their mother in the first hours of life. The womb is not a waiting room; it's a training ground.

Life before birth is not passive

We picture the womb as nine quiet months of floating. Ultrasound tells a different story: babies yawn, stretch, suck their thumbs, and rehearse nearly every skill they'll need on day one. In this video I share five of the most astonishing — each one a small rehearsal for life outside.

The five, in brief

They taste your meals. Flavours from your food pass into the amniotic fluid, your baby swallows it daily, and studies show newborns prefer flavours they 'ate' in the womb.
They practise breathing. From the second trimester, babies make breathing movements with fluid instead of air — training the muscles and maturing the lungs.
They hiccup. Those rhythmic little taps are hiccups — common, normal, and part of developing the diaphragm.
They dream. By the third trimester, babies spend time in REM sleep — the dream stage — helping wire the developing brain.
They learn your voice. Babies hear from around week 25–27, and your voice is the sound they know best. Newborns will turn toward it and are calmed by it.

What this means for you

Talking, singing, and reading to your bump is not silly — it's the first bonding your baby will ever experience. Partners too: a voice heard regularly in the womb is a familiar voice at birth. It's one of the quiet miracles of pregnancy, and it costs nothing.

Common questions

When can my baby hear me?

The ears are formed by around week 18–20 and babies begin responding to sounds around weeks 25–27. Your voice reaches them best, carried through your own body.

Are hiccups in the womb normal every day?

Yes — many babies hiccup daily in the third trimester. It feels like small, regular, rhythmic pulses. Like everything in pregnancy, if movements change pattern or reduce, mention it to your provider.

Should I worry if my baby is quiet some days?

Babies have sleep cycles of up to about 90 minutes, so quiet spells are normal. What matters is your baby's overall pattern — any clear reduction in movements should always be checked the same day.
