I can't grow a decent mustache but I'm a walking hormone. I know that after giving birth a woman can go into postpartum depression. This will change how she looks because she will not have the vitality going on. More of a frown and a propensity to blow up at small incidents. Like spilt milk or me being 10 minutes late... or 10 minutes early. Postpartum depression or any kind of depression needs to be recognized by the new mother and the new father. If its left as a background influence it can cause bizarre behaviour that may be the turning point in a relationship. Postpartum depression can last up to 8 years if not addressed properly. Try a search on this for ways to ease out of the situation. Other morphological changes include a protruding bellybutton, stretch-marks, a separated coccyx or rearranged ilium. Some women will not give birth naturally and go with a C-section as well as bottle feed their offspring rather than nursing by breast. These practices can be employed in the hope of less changes to their morphology. But, the C-section has obvious implications to the look of the stomach and bottle-fed children are often the ones that keep a parent awake all night... thus producing pretty baggy eyes and further deepening Postpartum depression.
