Happy Thanksgiving! This blog revolves around obscure, fascinating, strange, and unusual diseases, but some days, we have to give thanks for the healthy.
You are a pediatrician evaluating a perfectly healthy baby. She can stand on one foot with some slight support, walk backward, and even go up stairs with one hand held. She scribbles spontaneously, picks up and drinks from a cup, fetches and carries objects, and finds a toy observed to be hidden under layers of covers. She periodically visually relocates her caregiver and has some self-consciousness, feeling embarrassed when she sees you observing her. She understands simple commands and uses 5-10 words.
Challenge: How old is she?
