I had to check this out for Madeline, who is at the "I must be the best at everything and do everything perfectly" stage right now.
Peter Reynolds' Ish tells the store of a young boy (the middle child) who learns to love his style of drawing with a little help from his little sister (and initially learns to think it's not good enough from his older brother). Lots of good lessons in this one, and I was right, Madeline loves it! Perhaps because many of her drawings are "ish." And, in my opinion, absolutely perfect because of it! Love Ish!!
