My kids attend(ed) Casa de Ninos, a bilangual Montessori for kids 1.5-6 yrs old. My 5 year old, now in kindergarten attended for one year and now can speak Spanish fairly well (coming from a non-speaking home). He'll continue with one day after school program to keep it up. My 2 yr old is soaking it all up on the few days he attends the full-immersion school. But better than the bilangual aspect, the kids are being cared for in an incredibly healthy and nurturing environment, learning important skills while building their self-esteem. They've been really flexible in schedules and can make just about anything work. I highly recommend Casa de Ninos! If you are paying for a daycare or preschool anyways, you might as well integrate a second language in and you're getting even more for your money! Thank you Casa de Ninos!
