Hello Dawn,
Thanks for writing in!
1.) We highly recommend that you switch to the Blank - No Container | Header, Footer page template first. For more details about the different page templates in the theme, please check this out:
2.) Edit your Family Travel page and in Cornerstone editor, you will insert the classic recent posts element to display the recent post items. You can filter out the post items related to your family travel only by inserting a category filter in the classic recent post element setting.
3.) And to link your button to the blog, you need to use “https://www.5losttogether.com/blog/” as the URL of the blog page assuming that you already have created the Blog page and set it as your Post Page or the Blog index. For more details, kindly check out this codex: https://wordpress.org/support/article/creating-a-static-front-page/
Hope this helps.
