Class size in LKG at Sri Gayatri e-Techno, Shaikpet, and is there a helper in the room?

We're looking at LKG options for our son, and Sri Gayatri e-Techno in Shaikpet is one of the schools on the list. Two schools so far have told me their LKG batches are 'small'. One of them, when I pressed, meant 30. So I'd like real numbers from current parents rather than the admission desk: roughly how many children in an LKG section, and how many adults in the room. Is there a helper besides the class teacher? My son still needs help opening his tiffin and getting his shoes on, and I want to know someone has time for that.
