Our baby is the size of a plum right now, has a heart beat of 174 and is just over 2 inches. It's right on track for growth. During the sonogram, Baby Plum did a lot of dancing, turning over and generally showing us a great view of the lungs expanding, the spinal column and its beautiful little feet and hands. It was definitely rockin' and a rollin' in my tummy. Chris actually got a little seasick during the process because the baby was moving so much.
