The sound of your voice has the most calming effect on your unborn child. One study found that foetuses respond to their mothers’ voices by slowing their movements, while another revealed that foetal and newborn heart rates decreased when their mothers spoke – a possible sign of relaxation3,4.
Talking and singing to your bump can be a lovely way to start building a relationship with your unborn baby and can benefit you as well as them. Incredibly, bonding with your bump can help your baby learn. But if you don’t feel comfortable with the idea, don't worry. While in your womb, your baby will hear and feel the vibrations of your voice every time you speak to anyone. They will have learnt to recognise and be comforted by your voice by the time they’re born, even if you don't speak to them directly4. This recognition will help them to bond with you and the sound will make them feel emotionally secure for many years to come.
