Miranda Kerr Turns 40, Calls Motherhood with Three Kids 'Most Incredibly Rewarding Experience'

The Australian model is reaching the big 4-0, and she is opening up about the great joy of being a mom to three wonderful children.

Miranda Kerr turns 40 years old this coming April 20 and expresses how motherhood has been "one of the most fulfilling parts" of her life.

In an exclusive video she shared with People magazine how she learns so much from her children every single day. Being a mom expands her heart and her soul as she becomes capable of giving more love and patiences and capable of showing more resilience than ever before.

"Becoming a mother to my three beautiful healthy boys is really the most incredibly rewarding experience of my life. Being a mother has taught me that I'm so much more capable of more than I actually thought I was capable of," expressed the businesswoman and founder of KORA Organics.

Favorite part as a mother

The 39 years old model and husband Evan Spiegel share four and three-year-old sons Hart and Myles respectively. She also has twelve-year-old son Flynn, whom she shares with former husband Orlando Bloom.

Kerr describes her three boys as "kind hearted," "good mannered," and "very sweet," unafraid to express their feelings toward her and tell her "I love you," regularly.

She admits to facing a lot of challenges being a mom, saying that there are really days in motherhood that are not easy, yet she has learned to try her best being patient, kind and nurturing.

On the red carpet of the 20th annual G'Day USA Arts Gala in Los Angeles last January, the mother of three revealed her favorite part as a mother.

"Just seeing the world through their eyes and the fact that they're all very different. They have different personalities, and they just bring something to the table that's just unique to them," she declared as quoted by The News.
