I had a period of behind effectively a stay at home dad and I disagree with this completely.
Being a stay at home parent doesn’t literally mean you have to stay at home. Take the kids and leave the house. Go on adventures. I met so many people randomly during that time.
It was vastly more social than sitting in an office or working from home alone.
I wasn't a SAHP but I'd spend time with my kids at a park nearby and people would give me dirty looks for playing with my kids if my wife wasn't present.
The internet convinced me it was going to be a problem, but it literally never happened once.
We rotate through parks because the kids love seeing new parks. Nobody has ever given me a dirty look for bringing my kids to the park. It’s a completely normal thing for parents to do.
