Alia Bhatt shared her experience of shooting for 'Rocky Aur Rani Kii Prem Kahaani' song 'Tum Kya Mile' after becoming a mother. She said though returning to work as new mother wasn't easy, she was "grateful" to be "supported by...team...that was understanding". "It was my baby girl's (Raha) first trip to Kashmir and seeing...mountains through her eyes was...everything," added Alia.
