Spay,
You give me hope! My DH is 37, and is a baker (which means he is a stay at home dad). He has yet to find his niche. When he goes to the park with my 3 yr old ds, other mothers watch him like he is going to snatch their kids! (Not that I can really blame them). Also - when at the park DH is not one to sit and watch - he gets in there are plays with ds and his friends.
He would love to join a playgroup, but they are all "mommy and me". He says he feels stupid going.
I so loves being a stay at home Dad! I wish he would find the perfect playgroup!
