On the left, where you see Nina's picture, there is a box underneath that says, "grab this button."
That is where you can copy the code and paste it on your own blog layout.
When you are in the blog layout, click on "add a gadget"
Then click save, and voila! All done. Then check your blog and make sure the link is actually working :)
If you want to, you could even write a little something about our family! :)
And if you do post Nina's button, will you leave me a comment and let me know? Thanks!
