The variety of activity seems to meet the needs of the different age groups and personalities of the children. As far as keeping your child focused with the rest of the group, I might try an incentive for him if he behaves. I really need help with keeping young ladies motivated, ages 16 -25, most of whom are new Christians, even our SS lessons are basic. I am not complaining because some times we grow stronger by reinforcing our foundation. Doesn't Celebrate Christmas Regarding the child that didn't celebrate Christmas.
All religions have some type of celebration.
One of the doctors that I worked for was muslim, during the month of Dec. they have Ramadan, they fast for a full month with celebration afterwards, but it is to help them be compassionate with people who are less fortunate. There is always the theme of Christmas around the world. Ramadan runs from November 27 through December 26. Last year some 20 million Christians were estimated to have prayed for Muslims during Ramadan. Only God knows all of the wonderful answers to those prayers.
