Little Julian was murdered two years ago along with Hudson's mother Darnell Donerson, and brother, Jason Hudson.
And the 29-year-old singer and actress said that the event helped her to keep Julian's memory alive.
She told Contact Music, 'This was a good way to keep Julian's memory alive by blessing other children through the holiday season.
'For us, we never had a sad Christmas, so we want to make other children's Christmas be as enjoyable as ours were growing up.'
Her sister, and Julian's mother, added, 'Julian always had toys. I would come home and see his bike down the street and say, 'Why is your bike down the street?' 'Oh I gave it away.' This would be right up his alley I think. I know he's smiling, something he would have done, exactly.'
