Blogging on 2 pages in one site/

I just helped my wife create her site at https://www.carriessweetlife.com The thing is she would like to have 2 blogs there. One for her cooking on the main page and a personal blog on another page. I have resolved the issue of creating and linking another page. Now I just need to figure out how she can make a post and pick which page it will go on. What is the easist way to go about this? I looked through some of the documentations but I think I am just to the side of them. Thank you in advance for the help on this.
