Not unless you have some older, more confident readers/actors for the main roles, but young children are ideal for the rest so just take on board the following points….
Most of the cast will have 1 or 2 rhyming lines to say, and those who have more tend to be repeated lines, so there are many parts which are suitable.
The singing will really appeal to young children as I have used tunes such as “Here we go round the Mulberry Bush” (This is the Way to Bethlehem), and “1,2,3,4,5 Once I caught a Fish Alive” (One, Two, Three Wise Men). See “The Day That Baby Jesus Came to Town” page for specific song details.
However, you would need to bear in mind that the main narration element is done by the Innkeeper’s wife (acting, but using her diary as a script), with interaction with the main innkeeper. These 2 parts are crucial to the flow of the script and would be beyond a young child as it involves ‘scan reading’ a large amount of lines, but could be taken by someone older, or even a teacher instead.
