Get invitations out for baby shower

Ok so I have written all of the invitations and sent them out for Heather's shower. She is my future sister in law. I'm looking forward to the shower but at the same time I'm dreading it. I was never fortunate to have my own kids. Even though, I now have two of the most wonderful kids in the world. I am still sad whenever I think of not having one. Infertility is one of the hardest things that I have had to go through.
