I would recommend a focus on nutrition now and during pregnancy.
In pregnancy, be sure to consume enough enough protein, complex carbs, and plenty of produce along with nutritional herbs (traditional pregnancy tea herbs such as RRL, nettle, oatstraw, lemon balm, peppermint/spearmint, etc). Another pregnancy favorite of mine is chlorophyll. Also, adequate salt intake to assist in necessary blood volume expansion.
In labor, be sure to stay well-hydrated, well-nourished and empty bladder regularly. Physiological pushing to avoid exhausting yourself and your uterus pushing may help. Bonding with baby with as little interruption as possible to get that nice hormonal cocktail going.
