You have a couple of options: you could have a close female
relative or friend accompany you, hopefully one who has given birth
and has had a positive experience. Optimally, she would also
be able to take childbirth preparation classes with you. (Here, by the way,
is the gateway to the Lamaze parent's site, which includes a link
to a page for finding a class as well as access to other
helpful resources and information.) Your other option, which
I highly recommend, is to hire a doula. Doulas are women trained
and experienced in labor support. You can find out more about
doulas here. If
finances are a problem, many, if not most, doulas will be willing
to work with you to come up with a plan that is mutually agreeable.
I feel certain that is especially true for someone such as
yourself whose partner is being deployed. And, of course, there is
nothing to prevent your opting for both.
