Congratulations!
You're probably already doing this, but can you channel some of this anxiety and impatience into preparing for the baby? People spend a lot of time an energy on nurseries and wardrobes, but here's a list of things I think may be more important:
* Do you have a pediatrician lined up? If not, take the time to interview a few. In Santa Cruz (lucky you!), you probably have the option to see more holistically oriented practitioners, if that interests you -- do some research and find a good fit.
* Work out. Seriously, the birth will be easier, and your time as a new mom, will go much more smoothly if you go into it fit. If you can take a prenatal yoga class, that's also a great way to meet other expectant moms and build a parenting community.
* Make sure you have the things the baby really, truly needs. Cutesy little hats and outfits? No. A matchy-matchy little nursery? No. 10 million wipes and then some? Now you're talking.
* Find out in advance about resources like lactation consultants, La Leche League groups, doulas if you want that -- all that stuff.
* Cook and freeze some nutritious meals NOW -- you'll thank yourself in 5 months' time. Just be sure to include dark, leafy greens -- you're going to need the iron.
* Listen to music! Your baby's ears will be fully developed within a month or two, and he/she will pick up on the rhythms and melodies you play. Some people listen to classical, some people choose specific music that represents their culture -- but listen to something. Whatever you play now will be your baby's best and truest lullaby upon birth.
