We've all heard that children have a much easier time learning a second language than adults, and immersion preschools and bilingual preschools in Los Angeles are a perfect place to start. Kids have a knack for picking things up quickly, and those little brains absorb a second language like a sponge. In some families, bilingual immersion comes easy. Parents or grandparents may speak to their kids in Spanish, German, Mandarin, or another language, and kids also hear a healthy dose of English outside the home. In these cases, a bilingual or immersion preschool reinforces the concepts taught by caretakers. 

However, if your family only speaks one language, a bilingual school or immersion school may be the only way to give your child the gift of a second language. These unique preschools infuse bilingual communication with the cultures and educational philosophies of other countries to give your kids a truly unique, diverse, and well-rounded experience. Immersion preschools can also help to prepare a child to attend one of LA's bilingual elementary schools.

The spiders are back! It's time to say buh-bye to the beautiful butterflies of the Butterfly Pavilion to make room for their slightly spookier friends.
