Soft play is not an adult friendly environment.
But seriously, it’s fine. I go to a lot of things where I’m the only dad or one of them, and yeah it can a feel a bit weird at first but in my experience none of that ever comes from the women. I think they mostly appreciate someone turning up without feeling the need to go full I AM BEING A DAD TODAY and turn up dressed as Spider-Man.
This is nothing to do with gender, but The main thing I find tricky is how to break out of parent chat and have real conversations or get to know other parents. That whole “oh you’ll meet loads of new friends when u have kids” has totally passed me by.
