Adding blog post from one blog into another WP site

Hi,

I have a dilemma that I hope you have a plugin to solve.

My client has a WP website for her home staging business and another WP website for her home staging training business.
She has another WP site that is her blog.

I would like the posts from her blog to be the "blog" for both of er other sites. I don't want to just link over to the blog because the styling of the sites are very different. I want to keep them on which ever site they are on.

Any ideas? Thanks so much for your help.
