Who is hiding in there? The bird thinks it's a cat because everyone keeps petting it. The cat thinks it's a mouse because Mama Lou is craving cheese. The brother thinks it's a boy, and a good soccer player too. And the sister thinks it's a doll she can dress up. Everyone has their own idea. "But I'm not any of those things!" the baby says from inside Mama's belly. "I'm me! Don't you understand?" No one can hear it. Until...WHAAA! The baby is tired of being ignored. It's time their voice was heard. Finally the guessing is over and the baby can show their family who they really are!
