Children's Activities?

What can a mother do with her children in both the winter and summer?  Organized sports and other activities?  Opportunity to mix with Mongolian children if attending an international school?  Ages 6 and 2.  Any indoor pools / recreation centres?  Organized pee-wee hockey?

Thanks!

There are expat mothers who organize indoor activities for their kids throughout the year. Mongolian kids do all kinds of fun things outside in the winter when the sun is out, but expat kids seem to miss out on the good stuff.
