That's cute! My very excited dd (almost 9) told my mom today. With my last pregnancy I sent my mom and sisters e-cards with a stork on them. They said "What are you doing June 24th."

My sister gave my mom a bouquet of lillies - one for each grandchild + 1 for the baby she was pregnant with. She then told my mom these were from the grandchildren. My mom got it right away, my dad took a while to figure it out!
