The beginnings of any childrenyou may have one day are already within you, so best to start feeding their beginnings now. Your health now will affect them physically and mentally. Building your nutritional stores and keeping free from toxins, and finding help in stressful times, will be valuable not only to your own health and ability but also to any children you may have.

Walking everywhere, growing their own food, carrying all their water, helped keep them healthy.
