That which is of paramount importance for the children, that which must precede all else, is to teach them the oneness of God and the Laws of God. For lacking this, the fear of God cannot be inculcated, and lacking the fear of God an infinity of odious and abominable actions will spring up, and sentiments will be uttered that transgress all bounds . . . parents must exert every effort to rear their offspring to be religious, for should the children not attain this greatest of adornments, they will not obey their parents, which in a certain sense means that they will not obey God. Indeed, such children will show no consideration to anyone, and will do exactly as they please.

Bahá’u’lláh, Bahá’í Education, p. 6

Also a father and mother endure the greatest troubles and hardships for their children; and often when the children have reached the age of maturity, the parents pass on to the other world. Rarely does it happen that a father and mother in this world see the reward of the care and trouble they have undergone for their children.

‘Abdu’l-Bahá, Some Answered Questions, p. 231-232

And further, those present should concern themselves with every means of training the girl children; with teaching the various branches of knowledge, good behaviour, a proper way of life, the cultivation of a good character, chastity and constancy, perseverance, strength, determination, firmness of purpose; with household management, the education of children, and whatever especially applieth to the needs of girls -- to the end that these girls, reared in the stronghold of all perfections, and with the protection of a goodly character, will, when they themselves become mothers, bring up their children from earliest infancy to have a good character and conduct themselves well.

‘Abdu’l-Bahá, Selections from the Writings of ‘Abdu’l-Bahá, p. 123

The material result is the children who are born in the cradle of love of God, who are nurtured by the breast of the knowledge of God, and who are brought up in the bosom of the gift of God, and who are fostered in the lap of the training of God. Such children are those of whom it was said by Christ, "Verily, they are the children of the Kingdom!"

‘Abdu’l-Bahá, Tablets of ‘Abdu’l-Bahá v3, p. 605-606

Shoghi Effendi was deeply saddened to learn from your letter... of the rather serious situation which your daughter's conduct and her general attitude towards the Cause have created... Although he highly deplores this fact, and is fully aware of the bad repercussions which it may have on the Cause, yet he feels that nothing short of your motherly care and love and of the counsels which you and the friends can give her, can effectively remedy this situation. Above all, you should be patient, and confident that your efforts to that end are being sustained and guided through the confirmations of Bahá’u’lláh. He is surely hearing your prayers, and will no doubt accept them, and thus hasten the gradual and complete materialization of your hopes and expectations for your daughter and for the Cause. The Guardian would advise you, therefore, not to take any drastic action with regard to your daughter's attendance at the meetings... For in this way, there is much greater chance to reform her character than through force or any other drastic method. Love and kindness have far greater influence than punishment upon the improvement of human character. The Guardian, therefore, trusts that by this means you will succeed in gradually introducing a fundamental change in your daughter's life, and also in making of her a better and truer believer. He is fervently praying on her behalf that she may fully attain this station.

Shoghi Effendi, The Compilation of Compilations vol. I, p. 300

And now we wish to address a few words to parents, who bear the primary responsibility for the upbringing of their children. We appeal to them to give constant attention to the spiritual education of their children. Some parents appear to think that this is the exclusive responsibility of the community; others believe that in order to preserve the independence of children to investigate truth, the Faith should not be taught to them. Still others feel inadequate to take on such a task. None of this is correct. The beloved Master has said that "it is enjoined upon the father and mother, as a duty, to strive with all effort to train the daughter and the son," adding that, "should they neglect this matter, they shall be held responsible and worthy of reproach in the presence of the stern Lord." Independent of the level of their education, parents are in a critical position to shape the spiritual development of their children. They should not ever underestimate their capacity to mold their children's moral character. For they exercise indispensable influence through the home environment they consciously create by their love of God, their striving to adhere to His laws, their spirit of service to His Cause, their lack of fanaticism, and their freedom from the corrosive effects of backbiting. Every parent who is a believer in the Blessed Beauty has the responsibility to conduct herself or himself in such a way as to elicit the spontaneous obedience to parents to which the Teachings attach so high a value. Of course, in addition to the efforts made at home, the parents should support Bahá’í children's classes provided by the community. It must be borne in mind, too, that children live in a world that informs them of harsh realities through direct experience with the horrors already described or through the unavoidable outpourings of the mass media. Many of them are thereby forced to mature prematurely, and among these are those who look for standards and discipline by which to guide their lives. Against this gloomy backdrop of a decadent society, Bahá’í children should shine as the emblems of a better future.

The Universal House of Justice, Ridván 157, 2000, p. 9

The members of the family all have duties and responsibilities towards one another and to the family as a whole, and these duties and responsibilities vary from member to member because of their natural relationships.  The parents have the inescapable duty to educate the children--but not vice versa; the children have the duty to obey their parents--the parents do not obey the children; the mother--not the father--bears the children, nurses them in babyhood, and is thus their first educator; hence daughters have a prior right to education over sons and, as the Guardian's secretary has written on his behalf, "The task of bringing up a Bahá’í child, as emphasized time and again in Bahá’í Writings, is the chief responsibility of the mother, whose unique privilege is indeed to create in her home such conditions as would be the most conducive to both his material and spiritual welfare and advancement.  The training which a child first receives through his mother constitutes the strongest foundation for his future development..."  A corollary of this responsibility of the mother is her right to be supported by her husband--a husband has no explicit right to be supported by his wife.

Up to the age of 15 years, children are under the direction of their parents.

What needs to be appreciated in this respect is the extent to which young minds are affected by the choices parents make for their own lives, when, no matter how unintentionally, no matter how innocently, such choices condone the passions of the world—its admiration for power, its adoration of status, its love of luxuries, its attachment to frivolous pursuits, its glorification of violence, and its obsession with self-gratification.

It is clear from the foregoing that the history of Bahá’u’lláh's family has two contrasting features: one, glory and faithfulness; the other, dishonour and treachery. Navvab, her two sons ‘Abdu’l-Bahá and the Purest Branch, and her daughter the Greatest Holy Leaf, shine brilliantly above the horizon of Bahá’u’lláh's Revelation and occupy immeasurably exalted positions within His Cause. The rest of the family including Mahd-i-'Ulya, Gawhar Khanum and their sons and daughters, all became darkened and perished spiritually, sinking miserably into ignominy and oblivion. This contrast of light and darkness, of good and evil in Bahá’u’lláh's own family is one of the most thought-provoking and mysterious features of His ministry. His eldest Son was the perfect mirror reflecting His light and the Centre of His mighty Covenant while another son turned into the 'centre of sedition' and the arch-breaker of that same Covenant.

Single parents often need training in how to be a single parent and how to interact effectively with the estranged parent, if there is voluntary or mandated contact, as well as education in what the needs of the children are in relation to the attitudes and behaviors of the parents.
