Congrats to you and your DH! Welcome baby Leo, Happy Birthday to you!
Wow, 10 pounds! I cannot imagine! My boys were 7lbs. 14 oz, and 7 lbs. 10 oz.
I predict that this guy is going to be the biggest though! Just by the way I am carrying and I am at 33+ weeks now!!!!
As for the sore nipples, ice packs and warm wash clothes and keep nursing through it. It will take a short time before they are toughened up. Ask your doc if it is okay for you to try Ibuprofen as well. Just temporarily, of course--to get you through the pain for now. It has the tendency to cause the baby's stomach to be irritated, but I can't remember if my son had any problems. I am pretty anti-medication usually.
Anyway sending you a big American Hug! Congrats again!
