Posterior High Placenta versus Anterior High Placenta
Her placenta is posterior (toward her spine), which means there's nothing to cushion the kicks. Her doc also said this may be why she wasn't showing much at this point. Mine is "anterior high" which means it's cushioning all the wiggles and jabs, and probably why I started showing right away. At the end of the day, having a high placenta is ideal. If the placenta is low, it could block the baby's exit and result in a C-section. Our placentas are in good shape.
So yay for high placentas!
