My wife has never stayed home with our son for an extended period, she has always worked. I, on the other hand, spent a year at home with my son, so no one gives me any shit. I also had a lot of little cousins that I used to care for. I wish some people would offer me help like I'm an idiot, I'd take them up on it to get out for a bit
Now back on subject, it is really a stupid stereotype, that is pervasive because I am avoided within a ten foot radius at the playground I take my son to. It seems to get better with age, I was completely ignored and avoided when he was an infant, but as he has gotten older, I guess the women feel it's ok for a guy to take a toddler to the park, because his wife will probably be at home to make us dinner and care for him the rest of the night?
