Book excerpt: A school day can be so overwhelming: so many people, so many noises, so many things to remember. Grown-ups say it’ll get easier with time, but even saying hello is incredibly hard. Thank goodness for comforts like math, for anything that can relax a restless mind. Maybe this time a few words will come out at last… An empathetic look at anxiety and overstimulation, It’s So Difficult follows a child throughout the challenging routines of a single day. Even the smallest step forward can be an enormous triumph.
