firstly congratulations! I bet your head must be spinning with everything to take in.
The best bit of advice i can give is to join a pregnancy board. I used the one on IVillage from about 6 weeks pregnant and now my son is 21 months old and Im still there (the pregnancy board changes to a mums board)
I expect you are due December so heres the link
http://messageboards.ivillage.co.uk/iv-ukpbdec 07 you will find many first time mums who have the same concerns as you do and the same questions. There will also be many 2nd, 3rd or 4th time mums willing to help with any info they can. You will share your stories and milestones and celebrate and comiserate with the many friends that you can make there. My board often have meets and families from all over the country arrive and have a wonderful weekend or day out with the children.
