Agate Surrey have made temporarily free (probably just until the weekend) at Amazon for US accounts a companion edition to the book they freebied upthread:
Diabetes Snacks, Treats, and Easy Eats for Kids: 130 Recipes for the Foods Kids Really Like to Eat by the same authors as the previous. While this doesn't seem to have the same level of medical dietary advice as the last one, at least it probably expands your circle of usable quick recipes?
