Moving to Dublin - need preschool - play/nature based

Hello!

I am moving to Dublin with a 3 year old and 8 month old baby (both boys).  I currently have my 3 year old enrolled at Waldorf School of the Peninsula in Los Altos; however, we are now moving.  I would love to find some type of similar school...I know Oakland has some options, but it looks like the commute would be a bit far...not sure - any advice here?  If there is a similar school, or at least one that is play based with a lot of outdoor play time, in the Dublin/Pleasanton/San Ramon area, please let me know.  

Thank you and appreciate any responses!
