I know time committment wise an NPC has a lot. But, correct me if I'm wrong, we can't discriminate against mothers can we?
Do you think it varies chapter to chapter?
One of my sisters, her chapter, actually initiated a young mom. The girl was actually a legacy to AOPi but her son became sick and went to RMH. So when she went to college she joined ADPi because of the RMH connection. My sister said she was a good sister, as active as she could be.
Depending on the school, the climate, the chapter, I honestly don't see the problem with a mom joining. As long as she understands the time committment, financial committment and willing to do it. Just my opinion.
