Sounds are more interesting than before

Voices, music and everyday noises are starting to stand out

The Millie's Team By The Millie's Team · Parenting Notes

Around week eighteen, your baby is paying more attention to the sounds around them. Voices, music and even everyday household noises seem to catch their interest in a new way.

What is happening

Your baby's hearing has been working since before birth, but their ability to focus on specific sounds is now growing. They are starting to tell familiar voices apart from new ones, and to notice when a sound stops or changes. This quiet listening is part of how they are learning that the world communicates.

Is this normal

Yes. Some babies turn their heads quickly toward sounds, others go very still and watch instead. Both are signs of the same listening work. There is no need for a baby to react in any particular way for this learning to be happening.

What helps right now

What to expect next

Over the next few weeks, your baby will start linking sounds with the people and things around them. This early listening is the foundation for babbling, and later for words. There is nothing to push along, just plenty of everyday talk to enjoy together.
