How do I know what the family needs? Cancel Se requiere un título

I'm relatively new to CI and have found this message board incredibly helpful. I've read about people helping with specific needs/projects for their children/families but am unsure where I would get this information for my child. Do I contact the CI office in Columbia? For smaller needs do I ask in my letter? I don't want to ask anything I'm not supposed to.  Any help and suggestions will be appreciated.  Thank you!!!
