You and your baby at 15 weeks pregnant

Your baby at 15 weeks

Around this time, your baby will start to hear – they may hear muted sounds from the outside world and any noises your digestive system makes, as well as the sound of your voice and heart.

The eyes also start to become sensitive to light. Even though your baby's eyes are closed, they may register a bright light outside your tummy.
