Hi,
I also live in South Barrington (south barrington lakes) and I have a little girl that will be 2 in March. The pediatrician I use is a practice called Lakeshore pediatrics. They are over by Good Shepherd Hospital off of 22. I am in the process of looking into preschools as well, so if you would like to share or compare information, feel free to email me directly- ____@____.com for recreational, I take my daughter to swim classes at prairie stone rec center. They are affiliated with the Hoffman Estates park district. South Barrington club has them as well, the times at prairie stone just happened to work better and we're members there too.
I take her to little village play place once in a while, you can check out their website. It's pretty fun for their age.
I would like to find some more things to do recreationally as well, that age group seems to be left out a little. Again, feel free to email me if you 'd like to share ideas.
Thanks and welcome to the neighborhood!
S.
