He needs new shoes and is too big for his shirt. He visits Sarah for little brother day at school.
Caillou is getting bigger! Caillou's feet are growing, so Mommy takes him to the shoe store where the salesman measures his feet, and Caillou gets a new pair of shoes. But he's not as big as Andre, who can ride a big bike, or Sarah, who is losing a tooth and waiting for the Tooth Fairy. Caillou is reassured he's growing when the growth chart shows how tall he has become. And, Caillou is too big for his favorite shirt, so he gives it to his favorite teddy bear to wear. On another day, Sarah invites Caillou to a little brother or sister day at school. The school is big and Caillou is a little afraid. But with Sarah's help Caillou has a lot of fun.
