When we lived in Austin, DH & I went to 2 support groups, they met monthly, we went almost every month. It was good for us to talk with other parents who had lost children. I made a few good friends through these groups.
A few months ago, I received an invitation to join a mother's group in our small town. Ethan goes to a church-run day care and a few ladies from the church organized this group. I went the first few months, they were still working out the plan - what would we do each month? Maybe it would have been different if I joined after they were already established, but it felt so wishy-washy to me. Some ladies suggested different crafts to do, quick recipes/grocery tips, fun things to do around town with the kids, etc... There was no focus.
In the grief support group, that was our common bond - grief over losing a child and everything that goes with it. We didn't have a topic of the month. We just shared what ever was going on in our lives. Some months, usually near holidays, we talked about how we planned to handle 'celebrating' those events, but often we just vented, and cried.
Maybe just being "a mom" is too broad of a term. Believe me, I get stressed, but this particular group I didn't click with. If I want to do crafts, I go into my craft room/guest bedroom and find a craft. Or I would join a craft group specifically. I felt like if I was stressed about parenting - say if Ethan was biting, I couldn't vent about that because a craft had been planned.
But usually if I'm stressed and need some adult time, I arrange for Ethan to stay with family while DH & I have a date night. Or I leave Ethan & DH at home while I have dinner & drinks with friends.
