AmnioNet About this site: See how a baby grows in the womb with ultrasound pictures that chart embryonic and fetal development. The site also examines potential complications at each stage of pregnancy and the safety of taking an amniocentesis test to check for chromosome defects. (http://www.amnionet.com/contents.htm)   Pluses: Pictures and graphs give an idea of what to expect at prenatal checkups.   Minuses: Images take a long time to download; frames make navigation difficult.   Best feature: A description of brain development explains how amnio tests can be used to detect such defects as Down syndrome.
