Hi Deepali ,
I heard Gunjan Play school in sector-62 is also from one of the good plays schools in this area. I don't know much about Maplebear . I feel play schools has nothing to do with admission process of your child in formal school so Play school should be very close to your home so that child doesn't has to spend unnecessary time in commuting . My opinion is, there should not be much strength in play school where child is studying because at this age children need individual attention of staff. I believe you visited the schools before shortlisting names because it is again very important that you visit the play school in working day to see the exact picture of school. Meet the principal, talk to teachers then decide . and now u have time for 2 months :) because now admission will be done in July ..
