Recently, the youngest Bachchan, Aaradhya Bachchan celebrated her fourth birthday. Grand-pa Amitabh Bachchan has given a special surprise to little Aaradhya. The kid is too close to grand-father Big B's heart and he has penned a very beautiful poem for Aaradhya. He posted it on his personal blog.

He wrote "Wonder is the element that provoked the human to discover, express, develop, imagine .. Wonder is the element that is obsessed by the presence it has generated in the eyes and nature of the child .. Wonder it is that becomes the greatest visible asset to one that can safely be classified in the realm of 'the child' .. And wonder it is that is enough evidence of the maturity in them that would always be termed, immature .. They are the world .. they are the 'being' that beckons for all that is known and unknown .. for all that needs attention and concern .. for all that has been looked upon as sensitive and of gift of nature .. they are the new born .. they are the toddlers .. they are the frocked and panted little geniuses .. they are our future and our present .. they are now .. we are then,"
