The Bollywood megastar shared an extreme throwback from 45 years ago. Big B took a trip down memory lane and dug out a photo of just-born Abhishek in the incubator with Amitabh admiringly looking at him at the hospital. "Just a few minutes into this world," Big B described the photo. "He has been wished. He has been decorated with the memories of his birth and connected in this world today on that flat piece of technology that has transformed the very existence of the human," the 78-year-old added in his blog post.
In a separate Instagram post, he shared then and now photos to write about what has changed since his son were young: "I led him once... holding his hand... he leads me now holding my hand," he wrote. "Love you, Pa," commented Abhishek Bachchan.
Meanwhile, Abhishek's niece Navya Naveli Nanda took to Instagram and wrote, "Happy birthday best friend to more NYC nights & Chelsea games. You may just be my favourite family member My partner in all crimes!"
