my only advice would be to enjoy being pregnant! As much as you wish to meet your new little one, don't wish away the days. Babies are wonderful but hard work and they are much easier in the tummy than out.
besides that, there is no advice to give. Only you will know what is best for you and the baby. I would say, always listen to the advice people give you after ethan comes along, but then, make up your own mind about what you will do.
as hard as it is, everyone woman has the ability to be a great mother. It does require sacrifice and some hard decisions every now and then and a mother can get to doubt herself and her abilities. Hang in there, take long baths and don't feel guilty about leaving the baby with loved ones. A mother needs a break every now and then, if she trulywants to be the best mother possible.
don't wory about the delivery :) it's going to happen, whether you're nervous or not. Try and be informed about all that will happen so that nothing is a surprise and then remember that it's only a moment in time and soon will only be a memory.
good luck!
