The 67-year-old actress's daughter Eva Amurri recently announced that she is expecting her first child with husband Kyle Martino, reported People magazine.
"I plan to just completely go against everything my daughter's trying to do and spoil them completely," Sarandon joked.
"I also can't wait for her to understand how challenging being a mother is and appreciate me even more when she finds out," she added.
The actress said she would not be sharing her motherly wisdom with her daughter as it will help her in learning things on her own.
