I first learned about sensory development when my son turned about 14 months old. This was right around the time when he started walking and getting into everything he wasn’t supposed to. His curiosity to touch, feel, and taste everything in sight prompted me to do a little research on this particular stage of his development. This is when I noticed the phrase “sensory play” became a common idea among mom bloggers, educators, and psychology blogs. It’s a phrase I think I’ve always heard but never really bothered to understand.
