The libraries have "toddler time" where they have stories read to them and get to have a little social setting. I take my son to the indoor toddler playground at Northeast Mall so he can play on a padded floor no matter what the weather's like, and there's always another child (or four) playing too. If the weather is nice, find a nice park (I'm surrounded by several: some have too many children that tend to be older kids, some are empty but nice for mom/son time, and there's another one that I LOVE that's never empty but is age-appropriate). Really, you just need to explore them and see. On Thursdays I go to a Bible Study and my church provides a few hours of free childcare there, and he LOVES playing with his friends at church, so maybe your church does something similar? I joined the HEB mom's club which was fun: it was active, always had something going on, and the children can play together then. We'd also go on "field trips" to "anywhere" (Grapevine for a train ride, Pet Smart for some free fun looking at the animals, etc). Really just keep an eye open for an opportunity: don't just walk past the salt water aquarium at the doctor's office or library, stop and take some time to watch and point things out and ask questions. The free magazines that you can find at the library or Tom Thumb (like Suburban Parent or Ft Worth Child, or whatever the local magazine is for your area) are GREAT resources for classes or events that are going on for the month at the zoo or....anywhere. There's a lot out there!
