AIM Infant Community

Hi! I would love more information about the infant community at AIM. I have my son on the waitlist, mostly because I intended for him to go to Berkeley International Montessori when he's 2.5 years old. I lived in Japan/speak Japanese so I'm primarily interested in the Japanese program. What does the AIM infant community look like? Any experiences? He won't be 18 months until the fall but I'd love any preliminary information. Thanks!
