HI there V.,
Well this is the right place to start. I made a few friends here on Mama source. I moved here about a year and a half ago from San Diego ca and I love it here. I had to find things to do on my own because my husband is always away from home for work. I take them to the childrens museum,the zoo, they have a toddler play area there where kids interact. The YMCA had sports for her age, put her in dance etc. Pick up the SAn ANtonio kids magazine from HEB, Borders book store etc. It is free and has many things for kids. Or meet new moms who have kids also. My boys are 2&3 and we have met new neighbors with kids etc. I am not sure if that has helped much. But good luck. You can also take her to a near by park to play on the swings,
Julie
