Telugu from class 1 at SR digi School, Hayathnagar? Our son hears only Gujarati and English at home

We may move to the Hayathnagar side next year for my partner's work, so we're looking at schools there for our younger one. At home we speak Gujarati and English; his Telugu is a handful of words from the building, and his older sister started Telugu late and found it hard going. If your children are in the lower classes there, is Telugu taught from class 1, and how do teachers handle children who don't speak it at home? Is there any extra support, or do most families arrange tuition? I'd rather hear how an ordinary week goes than what the admissions brochure says.
