The development of your baby's brain is a long, complicated process and although it started before birth, it won't be completed until they're a teenager.
When your baby is born, their brain is a quarter of its adult size.
Memory and the ability to remember develops over time but your baby will learn fast!
When they're only 10 days old, your baby can remember how you smell and by 3 months, they'll recognise you by sight
