We have lots to say about the importance of what we do...
Though your child may not master right vs. left until elementary school, there is still a benefit to introducing this concept at a young age! You may notice very early on that your child is favoring one side over the other when they reach for objects or turn around. By encouraging them to use both sides of the body you will help them to build strength on their non-dominant side which is helpful for overall body balance and strength.
In this video from the Little Beats from Home collection, Dani is singing a song to encourage using each side of the body in isolation. If you're looking to continue building your child's brain-body connection, check out Shoe A Little Horse from Intellidance which introduces cross-lateral movement. Cross lateral movement involves using BOTH sides of the body at once and strengthens the corpus callosum which is responsible for connecting the two hemispheres of the brain. Cross lateral movement practice supports emergent literacy – check out this video from "Active Learning with Rae" for more info on the benefits of cross-lateral movement at any age!
