. . or any day! When you're a mama penguin with lots (and lots) of little ones to take care of, the days can melt together in a blur. Monday: swimming lessons. Tuesday: sliding. Wednesday: waddling. And on and on. Mama loves her babies so much. Do they know, she wonders, just how much? As it turns out, they do--because they love her just as much! And to show it, they surprise her with a thoughtful gesture of their own on Sunday. In her companion to Baby Penguins Everywhere! Melissa Guion offers another adorable book for sharing between mother and child. A perfect Valentine's Day,  Mother's Day—or any day—gift for the person who is always there for us.
