Becky wasn't in my weight class

Becky just told me that she wasn't 8 pounds when she was born - about the same weight as me. She was only 6 pounds and 4 ounces. Now what does that mean for Josie? I was so ready for her to also be part of the 8 Pound Club. Now I might have to exchange her 8 Pound Club t-shirts for "Only 7 Pounds" onesies.
