My son just started Kindergarten, and he has already reached the “I know everything” phase of his life.

Normally this behavior peaks around 7 to 10 years old, but my kid has always been an overachiever. He started walking at eight months. He cut his baby teeth early, and he started losing them early too. At his last pediatric checkup, he sat comfortably in the 99th percentile for height. The boy is sharp, curious, and capable, but there is still an entire world he needs to learn.
