Young brains are perfect for language acquisition. The best way for your child to become bilingual is for one parent to speak exclusively in one language and the other parent in the other. For example, one parent speaks Spanish exclusively and one parent speaks English exclusively.
As a middle school Spanish teacher I have had access to Muzzy but have not used it because it's too young for my students. It certainly wouldn't hurt your preschooler to watch Muzzy but it will really only be effective if there is real life interaction/exposure to the language.
