ugh..i'm entirely too lazy to even attempt that..thankfully Fox's dad is a math whiz & physics major..i'm going to have him do it..hehe..i'll edit this in a bit with my prediction
**edited to say..
okay well i had him do it with Rory's info first..using her FULL gestational age..which was 39weeks6days..and it said 8.4 not too far off..she was 7lbs. 12oz.
so for Fox we just used the same days for gestation..just assuming he'll stay in as long..and it said 8.5..something. soooo hopefully that will mean he'll be around 7lbs. 14oz..that i can handle..lol
****EDITED AGAIN****
okay i'm starting to think Jeremy isn't as smart as he lets on..lol..jk.
but really..i decided to try this myself and i got..
7lbs. 8oz for Rory & 7lbs. 11oz for Fox
i think mine are right..lol
