i have been wtih Dr Dawkins for for the pregnancy and birth of my daughter and seeing him again for this pregnancy. he is laid back, and is very pro-natural pregnancy (ie does not wish to prescribe medication that is not proven to work, or prescribing things just for the sake of giving you something.) yet very knowledgable.
at the first scan (around 6 weeks) he will do a scan. he will take a bloodtest at the 11 week mark so that the results will be available at the 12week scan. this is a major scan and he will measure your baby (thighs, head circumference, tummy, etc) and calculate the risk of downs syndrome verom your scan vs the blood test.
he also will provide a dvd disk which you will bring to every appt and he will record the scan each time for you to keep. i still have my daughters and it is to amzing to watch as they grow in your tummy.
