Someone new is going to join Dora's family! It’s someone who sleeps in a cradle, drinks from a bottle, wears diapers, and likes to be rocked to sleep. Can you guess what it might be? That's right! Dora's mamí is having a baby and Dora is eagerly awaiting the new arrival - she just can't wait to be a big sister. But when Dora arrives to see the new baby, there's a big surprise waiting for her - twins! Now Dora has a baby brother and a baby sister.
