Play dates

My son is 14 months and I’d really like to have play dates for him because he doesn’t have any other kids around his age to interact with. He goes to a babysitter 2 days a week and her kids love playing with him but they’re much older like 6+ yrs. but that’s really it. And the biggest thing is, I don’t have any friends... so I don’t know how to go about doing this. I thought of asking on Facebook but idk. Any other mommas go through this? what did you do?
