What is a "family" worship service

We are having a "family" worship service on December 24th at 10am, and again on 31st. What does this mean? Basically:
1.) no long sermon
2.) no childcare except for wee ones
3.) entire service is singing & scripture readings
4.) the noise of children is expected (and appreciated, for the most part)
5.) the entire service lasts 50 minutes
