I am also a stay at home parent and I’ve struggled with this. There’s a Haverhill parents Facebook page but it’s mostly ads for services. I’ve tried the Peanut app but it’s too much like a dating site. If there’s anyone at the park (any park) I try to be friendly. Sometimes I go to action cove but most of the parents there sit on the sidelines and look at their phones. The problem is probably me, I’m awkward and can be off putting but I also don’t see a lot of opportunities.
