toddler play groups

Hi! We were transfered to Buenos Aires in August and are renting a house in Pilar- about 60km from downtown (we had been living in Houston, Texas). My husband commutes to the city daily.... We have a 2 year old and a 6 month old. Does anyone know of playgroups for toddlers out this way? I saw Gymboree just opened here, but I was also looking at other options. Thanks!
BAIN has a play group once a week in the suburbs of Buenos Aires. (Not as far out as Pilar though, more like San Isidro)
Their web just in case: www.bainnewcomers. org
Great! I actually e-mailed them a out 10 days ago to get information.... no news though. Any other way to contact BAIN? Thanks!
