29 weeks and ready

I'm 29 weeks and my pregnancy is very healthy. I am very happy that its healthy because with my first son I was in and out of the hospital and gave birth 5 weeks early. This time around I have not had any complications. I am just really tired and have really bad heartburn and having a very hard time sleeping. I am so ready to give birth but i still have 8 to 10 more weeks. I just want him to be born healthy. Then I'm concerned that Caleb is going to be too big for vaginal delivery, I definately dont want to have a c-section. I'm having a lot more anxiety about giving birth than I ever was with my fist son.
