Curious...

I gained way too much the first time, 50 lbs, baby was 9'4 I'm on track to gain recommended 30ish this time, I don't think he will be small, big babies run in the family and his dad and myself are tall, not small people. Also my sister gained less the second time and had a bigger baby

I gain between 40-45 with my last two and each were under 7.5 pounds 

I was wondering this too, my husband and I are pretty tall both 5'10 so I think she'll be long but weight size I don't know? I've gained 7 lbs and I'm 31 weeks. I was only to gain 15-20 so I'm right on track. Everyone says we'll have a huge baby and that kind of bugs me, no one really knows? Dr says I'm measuring right on track according to my weeks. 

I gained 40 with my first, I'm at the suggested weight but I have 11 weeks to go so I'm sure I'll be way over that. 😑

You also have to consider fluid retention, fluids and placenta. Your baby may only be 7.5lbs, but you could lose 15lbs at birth and then drop another 10 from retention.

I gained 25 1st pregnancy and had an almost 8 pound baby.... 

I gained 30 pounds with my son and he was 8 pounds 4 ounces I think baby's weight typically is an average of mommy and daddy's weight (with the exception being gd) 

My sister gained 20 and her baby was 8.7. I gained 24 and by baby was 6.11

I don't know if it's correlated. I gained almost 40 lbs last time and my baby was under six lbs.
