Gisele Bundchen has described her birth as the most "powerful experience" of her life.
The Brazilian supermodel says she never felt stronger than when she welcomed son Benjamin, her child with husband Tom Brady, into the world last December.
In a posting on her new blog (http://blog.giselebundchen.com.br), she wrote: "Giving birth was the most intense and life-changing experience of my life... I never felt so vulnerable but so strong at the same time.
"When he finally was placed into my arms, I looked into his precious eyes and felt an overwhelming, unconditional love. I felt a huge sense of accomplishment. 'We did it! We did it together!' He and I. I never felt so complete and empowered in my life."
Gisele delivered Benjamin at her and Tom's Beacon Hill penthouse, in Boston, and she admits the familiar surroundings helped keep her calm during the labor - which took place in the bathtub.
She added: "I was able to feel safe, blessed. I was allowing my mind and my body to let go and be free to experience the changes taking place within while surrounded by love."
The 29-year-old catwalk beauty hopes she will be as good a mother to Benjamin as her mom Vania Nonnenmacher was to her.
She explained: "My mom devoted her entire life to her family and did it with such grace. She couldn't have been more of a loving and caring mother. She is the reason why I believe that a woman is the core of a family. I can only hope to be for my kids what she will and always be for us."
