A staple part of daily life at the end of the autumn term in a primary school is the production of the Nativity play. In my last full time job, there was a tradition of using a real baby for Jesus. He (or she) lay in a full sized crib and was not touched by any of the other actors, so was quite safe and, oddly enough, there always seemed to be a new born candidate produced at just the right time.
In my present school, we are sticking to the artificial substitute and daily rehearsals include exhorting Joseph to pick the baby up gently and remember to support his head as he hands him to Mary. Producing a Nativity play with 22 children is a bit of a challenge - especially when it comes to crowd scenes, which have to be adapted slightly, but we're getting there. (Picture me, if you will, wearing my green visor, megaphone in hand.) Mind you, we are thinking of transforming one of the shepherds into a sheep if he continues to go AWOL - but then someone remembers that the shepherds are doubling up as the crowd, and if we did that, we'd only be left with a crowd of three. See, I told you some adaptations were necessary. Maybe a little imagination on the part of the audience will be helpful too.
