S.L.
What Jennifer M said is so true about weight being an estimate, even with the new ultra sound, etc. I would remember that God is in control of the situation and then relax and leave it there. I know so many people who were told their child had certain things and they were fine. On the other hand if there is a problem it's still in God's hands and you can do nothing about it so try not to worry and take it easy. Rest, eat right, etc.
