Just a swingin'

Your toddler may not allow you to rock them much anymore but most everything you do with them at a playground stimulates their vestibular system. Swinging, spinning on a merry go round and going down twisty slides is not only good exercise for their bodies but their brains too. 

"While in motion the brain acts like a flight simulator, constantly inventing, moving mental models to project on a changing world. This synthesis of proprioception, timing and sequencing, and kinesthetics is an extraordinary mentally complex operation and it builds thinking skills."
