The baby uses its limited magic skills to communicate with them in a very cute and clumsy way, and they all go on a journey filled with misunderstandings and fun moments.
One idea could be that Cosmo and Wanda's baby discovers a new magical power that no other fairy has. For example, the power to turn inanimate objects into living, talking creatures. This could lead to all sorts of adventures as the baby tries to control this new power and the chaos it causes in the fairy world.
A plot could revolve around the baby being kidnapped by an evil fairy who wants to use the baby's special connection to Cosmo and Wanda (as very powerful fairies) to gain more magic for himself. Cosmo and Wanda then have to go on a rescue mission, facing many challenges and using their combined powers and wits to get their baby back.
