grandma to be announcements??!

Mia🖤 • Mommy to my baby boy 1-13-2018💙👶🏻
When are you ladies planning on telling your parents that you're pregnant? My dad passed away last year in July and my boyfriends dad isn't in his life so it's just our moms. His mom is already a grandma but my mom isn't and this is her first grand child so I have to make it super special. And I have no clue how to even announce it. Help??
