My DH has been a SAHD for 7 yrs. In the past year he went back to grad. school, but he's still the one home during the day. One of his gripes was the weird stares at the park, but after our DD1 started preschool we cultivated a fantastic group of friends from there, some of whom also have non-traditional families, and that has been great. They all help each other out, rotate lunches and playdates, take care of each others kids in a pinch, etc. I am actually at home working in my office here full time, so I get to be in on the fun sometimes when I can get away.
