Your bouncing baby becomes a terrific toddler around the age of 12 months. Your toddler’s brain has reached an exciting but demanding next stage of growth.
The neocortex (‘upstairs brain’) is making trillions of connections, driven by your toddler’s constant investigation of the world around them. Your toddler is more mobile, enjoying doing more by themselves, and their communication is starting to increase through the appearance of many single words and gestures. You will notice that although they are happier to leave your side and explore, they still show you they need you when something is tricky or they want to celebrate what they can do! By the age of 3 years, your toddler’s brain will have reached around 90% of its adult size.
It’s not surprising that with all this busy growth activity, you will notice your toddler becoming frustrated at times with whoever or whatever gets in their way of having what they need (or want).
