"Every prayer for your family and your sweet little boy!" another couple posted a minute earlier.
"Their family is always so generous to others", Hanneman wrote on the Gofundme page.
Hanneman said the boy suffered life-threatening injuries.
Bloomington Police Chief, Jeffrey Potts said in a presser Saturday that the boy is alive but still in the hospital. Potts did not offer details about his condition.
Police are still searching for a motive. "Please know we will keep these items safe and handle them according to the family's wishes".
The child's mother asked everyone to pray, witnesses said, and security guards, patrons and police began performing CPR. "But as to why he did that, is still something we're looking into and trying to figure out".
Emmanuel Aranda, 24, of Minneapolis, is charged with attempted premeditated first-degree murder in Friday's attack.
Police said the child, who fell nearly 40 feet, has significant injuries.
"She was screaming, 'Everyone pray, everyone pray". Witness Brian Johnson told WCCO-TV that he heard a woman screaming about her child being tossed from the balcony.
"This is a horrific situation", Potts said.
In a statement Friday afternoon, the mall's management acknowledged the incident.
"'Very caring, very family-focused, deeply spiritual, very compassionate, extremely generous of their time, their talent and their resource", he said of the boy's family.
"The family doesn't know him and are completely clueless as to why this monster would target their family with this heinous act of violence".
A 5-year-old boy was thrown off a balcony three storeys high at the Mall of America.
The suspect, a 24-year-old man, was later caught and is now in custody. Court records show he was charged in two previous incidents at the mall and at one point had a trespass notice banning him from the mall.
Potts said one witness ran after Aranda as he fled the scene and tried to stop him. In this case, he started fighting with the restaurant's manager, causing frightened diners to leave, according to CNN.
The boy was thrown from the third-floor balcony at the Mall of America.
