Cute ways to tell mom?

Ericka • 30 years old. Married to my best friend 12/2010. Baby girls born 2016 & 2018... Hoping for a third 💕
I just got my BFP. Our original plan was to wait to tell anyone but now we realize how hard that is lol. I want to tell my mom tomorrow... Mind you she has been nagging for grandkids for four years so it's gotta be good. Any ideas???
