When Grandma comes for a visit, silliness and creativity are guaranteed, in this funny and endearing book by bestselling novelist Emma Straub; her kids' gaga, Susan Straub; and award-winning illustrator Jessica Love. Gaga days are the best! That's when this eccentric, mischievous grandma babysits her delighted granddaughter. These Gaga days are always full of the silliest "mistakes," like swapping eyeglasses and walking backwards to the park. Like making the house safe by eating all the marshmallow goblins, filling the tub to bursting with bubbles, and then reading a bedtime story all the way through upside down. With touches of Amelia Bedelia and Eloise, this irrepressible granny might just inspire deliciously goofy, endlessly creative, and bursting-with-love grandma-grandchild playdates!
