Dora has some really exciting news to tell us: Someone new is joining Dora's family! Someone who sleeps in a cradle, drinks from a bottle, wears diapers, and likes to be rocked to sleep. Can you guess who it is? That's right! A baby! Dora's Mami is having a baby! Maybe it's a boy or maybe it's a girl. Dora and Boots have to get home quickly to find out!
