We have a donor selected...she's 7 inches taller than me (I'm 5/3"). However DH's family consists of pretty tall people. His mom is 5'10".
My question is: DH was a big baby (8 lbs. 12 oz.). If we tx 2 and I end up with twins, could this be a disaster if perhaps donor's birthweight was also in the bigger category.
OR...does any of that even matter? I mean, maybe my MIL just had a really plentiful diet when she was p/g... lol.
I just wonder if this is something to consider. Don't want to have a terrible time trying to carry two longer/bigger babies. 
Thanks,
Monica
