Ideas on how to announce to family...

Shannon

So my fiance and I found out we are expecting late last month. We have only told his brother, my mother, my grandmother, and a few friends because we are heading to California in August to visit the rest of our family so want to wait to tell the rest of them in person.

Our first full day there, my future MIL will be throwing us a small engagement party that she's been planning for the last few months and since a good chunk of our close family will attending we plan to announce then.... but we have no idea how to do so while being sneaky about it leading up to it.

Any ideas? Should we just make an announcement? Throw it in while we thank everyone for coming? Put our pups in little "I'm gonna be a big sister" shirts and wait for someone to notice and freak out? lol. Any ideas are welcome!
