The March of Dimes has developed a laminated card that illustrates the differences in brain development at 35 and 40 weeks of pregnancy. In addition to the powerful visual of the increased brain size at 40 weeks, there are a few statements about the risks of preterm and late pre-term birth. The cards could be used as handouts, or you can scan a card to make a PowerPoint slide.
