A mother's physical and emotional well-being directly affects the inherited vitality and constitution of her children.

Original passage

If the mother is deprived of the care and comforts she should have, if she is allowed to exhaust her strength through overwork or through anxiety and gloom, her children will be robbed of the vital force and of the mental elasticity and cheerful buoyancy they should inherit. Far better will it be to make the mother's life bright and cheerful, to shield her from want, wearing labor, and depressing care, and let the children inherit good constitutions, so that they may battle their way through life with their own energetic strength.
