Your baby could hear your voice even before they were born — they were listening to you from inside the womb.

The Story

From about 18 weeks of pregnancy, a baby's ears begin to work. By 25 weeks, they can hear sounds from outside — your voice, music, even the rhythm of your heartbeat. Your heartbeat was the very first sound they ever heard.

Babies learn the sound of their mother's voice while still growing. When they are born, they already recognise it. Studies show that newborns will work harder — suck on a dummy more, turn their head further — to hear their mother's voice over a stranger's. They know you.

If you sang songs while pregnant, your baby may recognise them after birth. The melody, the rhythm, the particular warmth of your voice — all of this was being filed away, somewhere inside them, long before their eyes could see you clearly.

When does a baby first start hearing sounds inside the womb?

Today's Challenge

Lean close to your baby right now and say their name softly. Watch their face. Do they turn toward you? Do their eyes focus? They've known the sound of you since before they were born.

Talk About It

Tell me: what song do you think they heard most, before they were born?
They were listening to us all along — what do you wish we had told them?
Your voice is the first voice they ever heard. How does that feel?

Go Deeper

Newborns show a preference not just for their mother's voice, but for the language spoken during pregnancy. A French baby will respond more to French speech rhythms than a foreign language — they've already been learning the melody of their mother tongue.
