The mum of a three-month-old boy who died in the Bourke Street rampage has thanked the public for the love and kindness she has received, as a sixth person died following the incident.

A 33-year-old woman died in hospital on Monday night, Victoria Police said. The Blackburn South woman joins a 10-year-old girl, 25-year-old man, 33-year-old man, 32-year-old woman, and three-month-old Zachary Bryant as the casualties of the January 20 incident where a car was allegedly driven into crowds of pedestrians in Melbourne's CBD.

More than 30 others were initially taken to hospital, where nine remain, one in a critical condition.

Nawwar Hassan Bryant, Zachary's mother, posted a heartfelt message on Facebook paying tribute to her infant son and detailing the support she has received.

"Day 2 of being home and it isn't getting any easier -- yet. I know in time, it will, inshallah, but right now we are just missing our beautiful Zachary so much," Bryant said.

"Every move I make, every corner of the house and every sight we pass by reminds me of my child. Memories of him are so deeply etched in my mind I automatically connect something I see to a memory of him."

Bryant spoke of visiting the memorial site for the victims, and how she has been dealing with her loss.

"Amidst all this sadness I feel so grateful to know there is so much love and kindness all around us. I feel for parents who have lost their children, especially in war-torn countries, and feel extremely lucky to have all this support where I am," she wrote.

"We can choose to look at what we want to see and feel. I choose love, kindness and compassion. I feel I need these to heal and not anything else."

The memorial to the victims, which has grown to a massive size in the ten days since the attack, is to be removed on Tuesday. The huge mass of flowers will be mulched, Victorian Premier Daniel Andrews announced, and used at the state's Victims of Crime memorial.
