This Dr. has done a very good job of differentiating between the rarer condition of cranial synostosis and changes in head shape due to POSITIONAL MOLDING. She goes on to describe that parents may have gone overboard with postitioning a baby at sleep on the back in order to avoid SIDS and that side-sleeping is also acceptable and reduces risk aw well. Just as importantly she continues by reminding parents that babies should not be left in their little plastic seats and car seats all day long as this too contributes to positional molding of the head. Since there seems to have been a lot more about cranial synostosis both on Lactnet and LLLOL this was an excellent column to read. Mardrey Swenson DC, IBCLC
