Patricia MacLachlan has such a beautiful way with her words. Her book Who Loves Me? is the very simple story of a little girl asking her cat, who loves me? The cat tells the little girl all of the ways her family loves her until they are both tired and they snuggle up together and fall asleep. This is a wonderful way to reassure any child as to who loves them, young children will love thinking of way each of their family members love them too.
