The four-month-old settled into her maternal grandparents' home on July 10 to be cared for by the couple, Ruth and Darrell Madill, in Winnipeg in central Canada.
She is expected to need ongoing medical care.
'Ayla continues to make encouraging progress as assessed through comprehensive medical tests undertaken upon her arrival to hospital in Canada; and many follow up appointments are arranged for her over the coming weeks and months to monitor her future health status,' said a statement released by the family earlier this month.
'Current medical opinion is that, sadly, little Ayla will likely suffer ongoing disabilities the full extent of which cannot yet be known. Ayla will need intense ongoing care.'
On Tuesday, Nora Madill says doctors' expectations have not changed but it is still too soon to know definitely what Ayla's condition will be like into the future.
'She's still so little and she's still developing,' Ms Madill told The Dominion Post.
During Mr Collins' funeral service, All Black legend Lomu said the way Collins sacrificed his life for his daughter demonstrated the type of man he was, stuff.co.nz reported.
'Listening to the reports and what they say about how they found him - that he was protecting his baby - that's just typical Jerry,' Lomu said.
'He was a proud Porirua boy, a proud Samoan, but more importantly he was just a great man.'
Former All Black Chris Masoe said: 'When you realised what was coming and you protected Ayla from the impact with your arms and your whole body over her ... you made it possible for her to have a chance. That's the man you are.'
His father To'omata Frank Collins said it was clear his son was dearly loved, while his uncle spoke on behalf of the family saying that the former rugby union star had left them with a message.
'Life is so sweet and yet so short,' Collins' uncle Fr Lu Collins said, according to the NZ Herald.
'So love the life to the best you can. Do not waste the life you're living now.'
Tim Castle, Collins' manager and close friend told mourners of his fallen mate's ability to connect with anyone despite their age or background.
'He taught us all how to cherish each other and how to value difference,' Mr Castle said.
He described Collins as 'wicked, mischievous young man', and a giant 'with the most gentle and generous inner soul'.
