I finally had the bright idea of searching for blogs by Muslim mothers for more activities and such for Islamic holidays. Here are a few blogs and other links they led me to:
A Muslim Mother's Thoughts- her post for today has some sites to check out.
What I really need is a book with activities, stories, and Qur'anic verses for Islamic holidays. I found one at Amazon that looked pretty good, but it is geared toward people who know nothing about Islam, and that's not necessarily what I want- I don't need a book that spends half the time explaining Islam to me. Any suggestions?
