My DH is a SAHD and he came to Mothers Group with Amy and I before I went back to work. He now takes Amy to Playgroup and finds the mums friendly. We moved recently and I rang around the different groups in our area to find out which ones just sat around and drank coffee while the kids played and which ones were more interactive with their kids. We have found a great one, although I haven't been yet unfortunately because I work full time but hope to get there soon. Good luck!
