C.H.
I have a nine month old little boy, and live in LaGrange Park. The LaGrange Park Park District has great classes for moms and little ones. There is a class titled Best Friends which involves singing songs and such which is great. You can find their fall catalong online and can register online as well. My sister met a lot of area moms and tots through that class.
Although my little guy is only 9 months old (he is very social though!), I too am a working mom who would like more socialization. We belong to the zoo and are fans of the park.:)
