How Kids See the World

Major Milestones in Child Learning and Brain Development

As anyone who’s ever had the pleasure of babysitting knows, we don’t come into this world fully formed. Our bodies, our personalities and especially our minds evolve significantly throughout the first five years of our lives, driven by our growing capacity to learn and the anatomical development of our brains. Along the way, there are a few milestones that are more prominent than the rest in shaping how kids see the world.

Milestones From Birth to 5 Years Old (1)

People are born with all of the brain cells — or neurons — that they’ll have for the rest of their lives. Brain development involves making connections — or synapses — between these neurons, which enables complex movement, communication and thought. As unassuming as it may appear, this is exactly what babies are doing when they play, babble and smile. That’s why the behavior they exhibit at certain ages is so important: It reflects their internal development. Babies first build new synapses, then strengthen the useful ones, while allowing the lesser used ones to weaken. This is how, for example, the cacophony of babbling is refined into language.
