My LO is 14 months old and very active. We do one class a week but otherwise don't always get out that much.
I made a few friends whilst on maternity leave who I do still see on occasion, but since making the decision to become a stay at home mum I have realised that everyone else has gone back to work! It wasn't as noticeable over the summer (for some reason?!), but now it is clear I don't have a group.
I've found that most classes are aimed at younger babies (for mums on maternity leave) or older kids (at least 18 months) so I feel like we're in a bit of a limbo class wise, but also can't really afford to pay for endless classes. I have also found that people aren't that chatty after class.
I've tried a couple of playgroups but found them to either but very cliquey or very churchy.
I also try some of those mum social apps. But I don't drive so am somewhat restricted on locations.
What does everyone else do to find mums to hang out with?
