measurements

Amanda
My Di/Di girls are weighing a couple ounces of each other baby A 3lbs baby b 2lbs. I have roughly 6-7 weeks left (unless they decide to come early) have any other twins moms around this time frame have 6-7lbs babies at birth or were they around 5-6lbs? 
I know this is just a guess but I'm curious to see if other moms babies measured the same as my girls and came out measuring around 5-6lbs or higher.
