Martino took to Instagram to respond to "cruel" critics who criticised her for sharing her three months old son's story with everyone, reports usmagazine.com.
"To those who have expressed judgement, cruelty, and criticism of me, my choices, or my fragility during this time - I'm not going to justify myself to you," Martino, who is married to retired American soccer player Kyle Martino, wrote alongside a photograph of her cradling her son on Monday.
"But I sincerely wish that 2017 brings you enough self love and confidence that you no longer feel the need to tear down another person during their darkest moment," she added.
She also thanked those who offered kind words and support.
"Thank you from the bottom of my heart to everyone who has reached out with words of comfort or to share their own stories the past 24 hours," Martino said.
"It is so moving to know there are so many of you who are wishing our sweet boy well, and who are rooting us on as a family. ?I'd like to say one thing, which is that Parenthood is not a competition.
"Nobody gets an award at the end of all of it for doing it the best or most perfect way. All that matters is how we make our children feel, how we feel about them, and how we feel about ourselves as parents," she added.
