Some stories about Baha'u'llah's Childhood compiled by Hand of the Cause Mr. Furutan

Mansion of Baha'u'llah's father

* The mother of the Blessed Beauty was so enthralled with Him that she could not contain her amazement at His behaviour. 'This child never cries,' she would say; 'He is so unlike other babies who cry and scream and are forever restless while in the nursing stage . . .' 
(‘Abdu’l-Baha quoted by Ishraq-Khavari in Risaliy-i-Ayyam-i-Tis’ih p 62 in Stories of Baha’u’llah, compiled by Ali-Akbar Furutan)

* At the age of five or six the Blessed Beauty had a dream which He described to His father. In the dream He found Himself in a garden. Huge birds were attacking Him from every side, but were unable to inflict any harm. He then went to the sea and, as He was swimming, the birds of the air and the fish of the sea attacked Him, but He was not harmed. His father summoned a famous seer to interpret the dream. 'This dream-indicates', replied the seer, 'that the Child shall be the founder of a great Cause, and that all the leaders and learned men throughout the world will attack Him, but, like the birds and the fish, they shall do no harm. He will be victorious over all.’ 
(‘Abdu’l-Baha quoted by Ishraq-Khavari in Risaliy-i-Ayyam-i-Tis’ih p 65 in Stories of Baha’u’llah, compiled by Ali-Akbar Furutan)

* When Baha’u'llah was seven years old, one day His mother was watching the elegance of His bearing as He paced to and fro, and remarked 'He is somewhat short of stature.' but His father answered: 'It is of no importance. Are you not aware of His capacity and His abilities? Such intelligence! And such perception! He is as a flame of fire. Even at this young age He surpasses mature men.' Whenever difficult problems were discussed and no one seemed able to resolve them, the youthful Blessed Beauty would provide the solution. 
(‘Abdu’l-Baha quoted by Ishraq-Khavari in Risaliy-i-Ayyam-i-Tis’ih p 67 in Stories of Baha’u’llah, compiled by Ali-Akbar Furutan)

* While still a child, the Blessed Beauty watched as a government tax-collector, on three separate occasions, accosted His father and demanded, in a cruel and unjust manner, the payment of taxes. Unable to bear the injustice of it all, He, though in early childhood, mounted His horse and rode for two days until He arrived in Tihran. There, He sought the dismissal of this unjust and tyrannical tax-collector. He succeeded in obtaining the necessary papers ordering the dismissal, and returned to His parents.
