Announcing pregnancy to my girls

Tunisia • Mother of two little girls & engaged to my best friend
I was looking for a unique way to announce my pregnancy to my two daughters (6yrs old & 3yrs old). I came across a lot of pictures of a box filled with balloons to reveal the babies gender. So I did something like that, I wrote on the balloons (taped to the bottom of the box so they won't fly away) "mommy's having a baby."
