Eclipse Harmful to Pregnant Women: Myth or Truth? Pregnant women are advised not to come outside, eat or cook during a solar and lunar eclipse because people believe that it may have side effects on the growing baby. It is widely believed that an expectant mother should not go outside during an eclipse and not see with naked eyes. If they do, the child in the womb may develop some deformities. Do not use a knife or any sharp metal objects at the time of a lunar eclipse as it may cause the baby to have a cleft lip or birthmarks. Do not cook any food during an eclipse and avoid consuming food or water till the eclipse is over. Avoid any work during the time of eclipse and take rest as much as possible. Cover the windows with a thick curtain to avoid the rays of eclipse to enter. Is it true? I'm 6 months pregnant. 35 years old Worrying alot about my baby. Please advice.
