From The Book of Common Prayer:

For Families.

ALMIGHTY God, heavenly Father, who settest the solitary in families: We commend to thy continual care the homes in which thy people dwell. Put far from them, we beseech thee, every root of bitterness, the desire of vainglory, and the pride of life. Fill them with faith, virtue, knowledge, temperance, patience, godliness. Knit together in constant affection those who, in holy wedlock, have been made one flesh. Turn the hearts of parents to the children, and the hearts of the children to the parents; and so enkindle fervent charity among us all, that we may evermore be kindly affectioned to one another; through Jesus Christ our Lord. Amen.

For the Care of Children.

ALMIGHTY God, heavenly Father, you have blessed us with the joy and care of children; Give us calm strength and patient wisdom as we bring them up, that we may teach them to love whatever is just and true and good, following the example of their Saviour Jesus Christ. Amen.

For Young Persons

ALMIGHTY God, heavenly Father, you see your children growing up in an unsteady and confusing world: Show them that your ways give more life than the ways of the world, and that following you is better than chasing after selfish goals. Help them to take failure, not as a measure of their worth, but as a chance for a new start. Give them strength to hold their faith in you, and to keep alive their joy in your creation; through Jesus Christ Our Lord. Amen.

For a Birthday.

WATCH over thy child, O Lord, as his days increase; bless and guide him wherever he may be, keeping him unspotted from the world. Strengthen him when he stands; comfort him when discouraged or sorrowful; raise him up if he fall; and in his heart may thy peace which passeth understanding abide all the days of his life; through Jesus Christ our Lord. Amen.
