L.B.
I have two favorites that kids ask for again and again when we read them at my preschool-
"When Sophie get Angry, really, really angry" by Molly Bang, where Sophie gets so mad she runs and runs and finds a quiet place, in this case outside, to calm herself
and "Sometimes I'm Bombaloo" by Rachel Vail where Kate throws her own little tantrum and becomes someone named "Bombaloo" but in the end mom helps her pull things together with a little time out and lots of love.
Both of these are wonderful and really reflect the intense feeling of anger in children and then show how these two girls could calm down and come back with a fresh heart!
