What support systems are there for pregnant women?

Childbirth classes: Call your hospital and ask about childbirth classes. This is a good way to meet women in your shoes. Also cal the la leche league.

Start with family: Developing a network for support is similar to developing a network of friends, coworkers. However, a woman who is pregnant is vulnerable in some ways so needs to be more cautious whom she friends irl or using social media. I suggest she not share real names, locations, the due date, plans for delivery, gender of the baby, ultrasound photos, etc. On websites or with people she does not know well.
