Leandro is doing well and weighs a healthy 5kg. "He looks like a 3-month-old because he's drinking so much. He has 150ml every four hours. He's very greedy."
Gayo says he is grateful for the support of members of the New Zealand Filipino community. Gayo has no family in New Zealand but friends visit every day, cooking, cleaning and helping with Leandro.
The financial burden from not working for six weeks, the cost of returning to the Philippines and Leah's funeral has been eased by the generosity of the community, which has donated $10,600.
"It's such a blessing to me. I just want to say thank you to all the people who have helped me."
Gayo has not yet decided whether to complain to the health and disability commissioner, and is struggling with a promise he made to his wife that he would remain in New Zealand.
Auckland District Health Board spokeswoman Jennifer Dann said the board was investigating the circumstances leading to Leah Gayo's death and no comment would be made until that was complete.
They invited Gayo again to meet them, Dann said.
