This was our situation too. DD1 is in her third year at the school and DD2 in her second. They had absolutely no exposure to religion whatsoever before attending the school but neither has had a problem adjusting. TBH the only one with the problem is me. I was perhaps naïve at just the amount of religion that would be in their day to day activities, the focus of assemblies etc - particularly given that the school takes people of any or no religious denominations - and I am struggling a little with the extent of it. I am doing my best to support the teachings of the school, as we are obligated to do given the contract we entered into with the school, while still giving my kids the balanced outlook I think is appropriate.

Oh, and the school library is full of age appropriate children's bibles, as well as little books with individual bible stories which they frequently bring home so I wouldn't worry about buying one yourself unless your DS asks for one down the track.
