Washington was a guest of honor at the Baby2Baby Gala in Culver City, California, on Saturday, where she opened up to ET about how motherhood has changed her life dramatically.
"You know it just turns your world upside down in the most beautiful way," the 38-year-old actress shared.
"She makes me better, I hope, every day. I feel very lucky to be her mom," Washington gushed over her 16-month-old little girl with her husband, NFL player Nnamdi Asomugha.
In terms of advice for other new moms, Washington emphasized the importance of honesty and openness among mothers in terms of both advice and mistakes.
"I just think it's really important to share," Washington said. "It's really useful when, as moms, we can be honest about our process because it's so challenging. I really love being a part of this community of moms in the world now, where we get to share our experience in this magical adventure."
The star-studded event celebrated the non-profit organization Baby2Baby, which provides low-income families with basic baby necessities such as diapers and clothing. Washington was honored at the dinner with the Giving Tree Award for her support of the charity.
