Roteiro: Pediatric textbooks describe the ability to "roll over" as appearing 10 to 20 weeks after birth. However, this impressive coordination is displayed much earlier in the low-gravity environment of the fluid-filled amniotic sac. Only the lack of strength required to overcome the higher gravitational force outside the uterus prevents newborns from rolling over. |
