They're whoppers!
Those girls are packed so tightly in there that we couldn't see much on the ultrasound today, but Noreen was able to tell us that Baby Uno is 5 lbs 13 oz and Baby Dos is 6 lbs 3 oz, with a standard deviation of 10%. If Erin were to carry full term, they'd likely be 8 lbs or more, but it's not likely that she'll go much more than two weeks. The clock keeps ticking....
