HELP MOMMIES: 2nd time mom in the making

Megan

I currently have an 18 month old. My in laws weren't very happy when we broke the news about our first child. I took a test & it was positive. Anyone know of how to tell them & them not go on a rant about us having a second child? C'mon mommies, my mom is excited for another grandchild, as my sister is pregnant too.
