How to Announce...

Lacey

I will be 12 weeks on Friday. I have an 8 year old stepson, a 6 year old daughter, and a 17 month old son. I want to finally tell them that they are having another sibling. Our last one. We are going to a huge pumpkin patch this weekend and I'm trying to think of a cute way to tell them while we are there. Any ideas will be greatly appreciated!
