"He was supposed to stay for the night but that turned into a week," Benioni said.
On Friday, November 4, Benioni received the phone call that would change her life forever. "We got to Middlemore and we got the bad news that my son wasn't going to make it," Benioni said.
"At the hospital they said it was a skull fracture and they kept saying he wasn't going to make it.
"He had tubes everywhere but it was like he was gone, he was already dead. We waited 'til the Sunday and then turned off life support. It was hard."
Benioni said she was told he'd been injured at the god-parents' Otahuhu house six hours earlier.
"They [the godparents] said he had a seizure and he leaped for a mirror that was in front of him. But there are so many stories coming I don't know what to do."
Benioni said she and her partner were barely coping but were being assisted by their families and the Cook Island community. "I have my family for support. I have been out a lot to see his grave. Even if I have to catch a bus or taxi."
Benioni still had the box of her son's birthday presents, most of them unopened.
"He had a chance to open two of them. One was a little dog that barks, he loved that."
She also cherishes a rattling ball her son was playing with before he went away.
"The other day I heard that ball rattling and there was no one else in there so I know my son is with me in spirit," Benioni said. She was sorry she ever let her son out of her sight.
"I have got a lot of regrets. If I could turn back time I wouldn't have handed my son over at all," Benioni said.
The godparents have since moved from the Otahuhu home where Popo died and are staying with family in Otara.
The Herald on Sunday understood their three children - all aged under 10 years - were in the house at the time Popo was injured.
