meeting new people

I've been trying to meet up with some new people from post. I want to know more people here so that I can decide if I want to stay here, move to post, or go home when Tony deploys. There seem to be many people out here and I'm always finding people that live in the area. I have a play date set up with another mom with 4 boys on Thursday. And then another one I met said she wanted to get together and meet new people, but then when I message her about doing anything she doesn't seem to want to commit which is fine. However today when she responded she mentioned that she is looking for people to do an under 4 playdate with. I guess I understand, but that's weird. All boys cool, large families cool, but all little kids makes me wonder what people think of older kids. lol
