Eight-year-old Nadia's note reads:
"Dear Santa Claus,
Since you've been giving us presents every year, this year I ask for nothing.
I have toys, a home, family and love.
So this year I want to make you something.
Tell me what you want this year and I'll make it.
Love Nadia."
The sweet note warmed the hearts of thousands online, with a lot of people praising Nadia's parents for "raising such a wonderful child."
"What a sweet soul this girl has," one Facebook user replied to the post.
"That's so sweet! In our house we always leave a few things for Santa to take with him for those less fortunate," another responded.
"Totally melts my heart. What a great little girl," Facebook user Jen O'Leary wrote.
Ms Prado, who was clearly overwhelmed by the hundreds of comments from kind strangers, responded with a photo of her "fun loving, happy" girl who "genuinely loves everybody."
