I am teaching in a Reception class where 25 out of 30 children do not celebrate Christmas. We are having a Christmas Nativity play and putting up decorations and we are doing cross-curricular learning on the Nativity but I am reluctant to spend the next three weeks on making Christmas decorations and festooning the class which my partner teacher seems to want to do (we plan together for both classes) and would rather plan learning in accordance with the children's interests. In these circumstances, would it seem odd if I reduced the focus on Christmas?
