I love watching my daughter experience new things, and providing new experiences for her to try. This summer as our crunchy grass needed water, I stuck her feet and hands in front of the sprinkler. She discovered the tickly pressure of the water between her fingers and toes. The first time she met grass and sand, she didn’t want to put her hands down, the feel foreign and strange beneath her fingertips. And then everything started going into her mouth. Rocks, leaves, random particles left on the floor, and even her toes. It used to drive me crazy, having to constantly supervise what she was picking up because it inevitably would end up in her mouth. But she was exploring her world, discovering the tastes, feels, and smells all for the first time. It is how babies learn, and yeah, boosts their immune system all at once.
