Your baby’s brain at 0 - 3 months

0 - 3 months: your baby's brain

Sights and sounds all contribute to your baby's early brain development. Learn why good nutrition is important too.

Although your baby might not be very responsive to outside stimulation (other than feeding and cuddles!) when newborn, by 3 months they’ll become more reactive. You’ll probably notice that loud noises will startle your baby or make them cry, but your familiar voice should quickly comfort them! As their brain develops they’ll start to become very curious about what’s going on around them, and use as many senses as they can to explore their world.
