"Thank you all so much..for all the blessings, greetings and good wishes...yeh sach hai ki pota Dada ke liye uska bachpan lekar aata hai ...wrote a well wisher... (Its true that a grandchild brings along with it the child in the grandfather) and I could not agree more with this," Bachchan wrote on his blog.
"On many an occasion we reminisce the time we lost in not being as much as we wanted to be with our children..could somehow be compensated. Well, this is that moment of compensation. To be a child again, to pamper and give love and company and all things bright and beautiful to the little one that shall take over all our attention in the days to come," Big B said.
Last night, the 68-year-old actor, broke the news of his daughter-in-law Aishwarya Rai being pregnant through a social networking site.
"And so to becoming a Dada! The excitement and the joy of the first Bachchan coming after my brother and me. Nana I was, but now Dada!! The doctors just confirmed it this evening and I have shared it immediately," he said.
Bachchan is delighted that the legacy of his late father Dr Harivansh Rai Bachchan, a well-known Hindi poet, will be continued. .
"There is joy and happiness around us. The legacy of my Father lives on. My Father and my Mother brought forth two sons - Amitabh and Ajitabh. Amitabh had two -- Shweta and Abhishek. Ajitabh had four, Nilima, Namrata, Naina and Bhim, who are yet to be married. My daughter is and has two children--Navya and Agastya-- now cometh the progeny of my son that shall bear the surname Bachchan - the first in this generation," Big B said.
"My parents that reside in our hearts and above shall be most pleased and happy to see the family grow - a family that they started with care and love. We take responsibility of continuance and feel a sense of pride and promise as we think of the coming days...the growth of a family...the growth of a legacy...the growth of another generation," he said.
