find a mom with children

Hello, I'm Eun-Young, 38 year-old working mom of two children (ages 2, 5).
I got a Master's degree in intellectual property from a law school in the US last
year, but my English is not so fluent, I think.
So, I would like to find a female language exchange partner.
It would be nice to have a mom with children as my language partner, because
my 5 year-old son also wants to make foreign friends. He just started learning
English.
I live in Mia dong(subway no. 4 line) and my office is in Chung-mu-ro.
