We had been trying to tell Fred's sister about the pregnancy for a few weeks, but we kept getting delayed.
I searched my brain for a good, creative way. Finally, I just came up with printing a picture of an ant and writing “Linda” under it. We were going to give it to her and ask her to help us solve a brain teaser. I printed that paper and carried in my purse a few weeks before the actual date.
We got to their house and his sister had so much to talk about, we could barely get a word in! Finally, we asked Fred's mother to go play with his niece to distract her (since we weren't ready to tell the kids yet) and we were able to get his sister alone.
Fred asked if she would help with a brain teaser and handed her the folded paper. She opened it up and screamed “I’m going to be an ant?!”. We shushed her and his niece (from the other room) said, “what?”. His sister quickly made up something about having ants in our house (which we don't, btw) and it wasn't questioned.
Here is the picture we gave her below.
