have multiple websites need multiple blogs

Hi there,

I have several sites running now and have been using wordpress for my main site at https://www.autismsocialstories.com/blog. This has worked really well and I am finding wordpress good to use.

However I now want to set up a blog in the same format for my other sites, but I do not have a clue how to do this. My main sites blog was set up for me by one of the administrators here at wordpress.

I want to try and get to grips with how to do this myself, so can anyone please explain how I can do this? Would I need to install more than one download of wordpress, i.e one for each site? or can each sites blog be administered through the same control panel? This is what I would like to do if at all possible?

Thanks for taking the time to read the post, and I hope someone out there can help me please
