The 29-year-old, who raises the child with actor husband Orlando Bloom, said she likes nothing better than getting to spend the day with the youngster, reported Hollywood Life.
"What's surprised me most is just how incredible the bond is between you and your child. To watch him grow and evolve every day is really inspiring.
"(My perfect day is) to wake up to the sound of my son saying 'Mama, mama!' It's the best sound ever. Then I just love to get him out of bed and he can jump into bed with us, and we have cuddle time," she said.
The Victoria's Secret model also said she and Bloom would love to have more kids.
"I think probably, yes. Having a child is the most incredible experience," she added.
