Baby Jake is a nine-month-old baby boy and the youngest of 10 children who live in a windmill with their parents. At the heart of the show is the relationship between Baby Jake and Isaac, Jake’s six-year-old brother. Isaac is the narrator on the show and can understand all of Baby Jake’s giggles and gurgles. Isaac also opens the door to an imaginary world where Baby Jake sings, dances and baby-talks with his animal friends Pengy Quin, Sydney the Monkey, Nibbles the Rabbit and the Hamsternauts.
