At 9 weeks pregnant, your baby's ears are starting to develop, but they may not be fully functional yet. While it is still uncertain whether they can hear you clearly at this stage, research suggests that babies can detect sound vibrations and respond to them in some way. It is never too early to start bonding with your baby, so talking to them during this time can help create a connection and familiarize them with your voice. As the pregnancy progresses and their hearing improves, they will become more responsive to external sounds. So go ahead and talk, sing or read aloud to your little one – it's a beautiful way to begin building that special bond with your baby.
