I came across this site http://paganwiccan.about.com/od/wiccanandpaganrituals/ht/New_Moon.htm?nl=1 and I thought it was really nice in how it explained this. I was planning myself on doing something on the first New Moon of the year as it is something special and dear. I thought this would be nice to share with you all that you could use and maybe altar in some way to use with your kids to celebrate the New Moon; which is the 8th of January.
Brightest Blessings!
