My twins ended up one pound different when they were born at 38 weeks. My son measured larger than my daughter the entire time, but came out smaller! Both ended up smaller than estimated by the US (estimated at 6.5 lbs, but DS was 4 lb 15 oz and DD was 5 lb 15 oz). After my experience I just don't put much stock in the weight estimates. DS was always transverse and facing my back, too, so he was hard to measure. He was also long and skinny, which sort of "tricked" the machines' calculations. That said, we aren't entirely sure if the measurements were always wrong, or if he stopped growing at the end. His placenta was "less juicy" (my OB's term) that DD's so that could have something to do with it. Both my kids are thriving at 18 months and DS is several pounds bigger than DD now! You'd never know he was teeny tiny at birth! One thing to keep in mind is that depending on which baby is twin A, you may not be allowed to deliver vaginally if baby B is measuring much larger than baby A. You want the bigger baby to come out first to pave the way, sort of. I was allowed to try vaginally even though DS (baby B) was measuring larger because the difference wasn't supposed to be much. It turned out I had one vaginally and one c sec, but that was for totally different reasons!
