She had a small baby and was a big girl, 5"11... my sister had 8 pounders and hardly showed when she was pregnant because she is so tall.
I had an 8 1/2 pound baby and I looked like I swallowed a basketball at 8 to 9 months pregnancy. I was not a tiny gal either. But who knows...lots of women today try to keep their weight down during pregnancy and ANS being an addict likely did that without really trying.
