I'm baking a porker!

I had a growth ultrasound today and baby is measuring 7 lb 2 oz already! Since I still have three weeks to go and baby gains 1/2 lb a week they are estimating this baby to be 8 lb 10 oz. I know it's just a guesstimate but it's still pretty scary. I should probably buy some more 0-3 mo onesies since it looks like this little one might not fit into newborn size clothes.
