Most moms and moms-to-be have been to babycenter.com. It includes tons of information on anything related to pregnancy, birth and babies.
It's a great resource for all kinds of answers on all the stages of pregnancy and on what to expect as the pregnancy progresses. It also has expert advice on how to know when something is not normal and what to do about it. The information on babies is just as extensive with answers provided by moms and experts alike.
The website also provides email newsletters with tips and news as well as personalized weekly emails detailing your pregnancy stage. Once your baby is born you continue to get the weekly emails focused on the developmental stages of the child week by week. The emails also contain news, recall information and lots of baby tips.
Babycenter.com is one of the most complete websites on babies and pregnancy available today. I highly recommend visiting and signing up for any new mom or soon to be mom who likes to stay informed.
