My mil had a parenting book club when her kids were little and I love the idea. I want to start one but I am intimidated! Who do you invite? How do you use it to expand your social circle? I am not sure all of my parent friends will even be interested. I may start with articles like this post suggests: http://joannagoddard.blogspot.com/search?q=Article+club
So what should I consider? How many people is ideal? What time/days are best for moms with little ones?
