What To Expect When You're Expecting has a very good website, it tells you week by week what is happening with the baby's growth and how the mothers body is changing etc. I found it really helpful with my first and I'm using it again with my 2nd, I'm 8 weeks pregnant right now. Up The Duff - by Kaz Cook, is a hilarious week by week guide to pregnancy written by an Australian and it has help numbers at the end of each chapter if you need them.
The best thing I think I did while I was pregnant (and breastfeeding) was take the vitamins everyday, because it gave me the peace of mind I was doing the best for the baby, because I was so sick I couldn't eat properly. Also the neuchal (spelling?) translucency scan you have at 12 weeks (to scan for downs syndrome) decide if you want it, and don't let it be forced on you.
At the birth, be specific who you want in the room and what you want to happen. Who you want to cut the cord, what pain relief you want etc. (Write a birth plan!) My partner wasn't asked to cut the cord by the midwife because I was too high on the gas and too shy to speak up, so he missed out, also I just wanted him and me (and the midwife) in the room and somehow 2 other people managed to get in and I wasn't happy, I didn't want to share my birth experience with other people. Also decide before the baby is born if you want to breastfeed or bottlefeed, most maternity hospitals are very pushy with the breastfeeding and have been known to almost force it on women and it can really upset them if they cant (for any reason) manage to do it. Don't be guilted. But at least give breastfeeding a good thought.
When bubs is home, get a monitor and put it in its own room from the get go. My son was in my room till 8weeks when he started sleeping through the night, and I woke up to every little grunt and sniffle thinking he was choking. I was a walking sleep deprived zombie for 8 weeks, even though my son slept really well. And to all the bashers of the 'baby talk', babies actually love it when they are little, they love the stupid expressions and faces and silly voices we do to them, don't talk to them like that all the time, but a little bit when you have some quiet time is actually good for their development.
Child, Youth and Women's Health Services are an excellent source of information, try their website, they have lots of fact sheets for every little thing you can think of, plus in certain circumstances (mum under the age of 20, post natal depression etc) they will visit you at your house periodically until the baby is 2 and help with anything you need. They are fantastic! I thank my Child Health Nurse for my sanity. Also join a mums group, the kids love it and the mothers get some adult time!
Good luck, and enjoy them while they are little, coz they will be sullen grumpy teenagers before you know it.
