holding my breath

Tomorrow morning we have the "big" ultrasound. The one where they determine if all the parts are there, and if the baby's heart is healthy. I'm nervous, as we found out at 18 weeks that Charlie had something wrong with his heart. I held my breath before Kate and Maggie's ultrasounds; hoping and praying for healthy hearts. I hold my breath once again. I pray this baby has a healthy heart and healthy body.
