Jenny wrote this liturgy with a desire to create some space for prayer and contemplation in an otherwise busy time. There are two sets, one suitable for adults and one that is adapted to fit a family with younger children.

The adult one has five stages - last thing on Christmas eve, first thing Christmas morning, before the meal, at tea time and then in the evening. 

The family one has the same first and last stages - assuming that probably smaller kids would be in bed at those points - and other sections are simplified or removed.
