I'd like to find a local support group for MLC spouses, but they're kind of thin on the ground. I'm still reading as much as I can on the topic and educating myself as much as I can.
If you can find other LBS and meet with them it is one of the most empowering things that you can DO. As far as MLC education their is a ton of stuff around, this website has great resources and it is a good place to start. If you need any help finding something I may be able to point you in the right direction.
