Zachary Bryant was the most perfect baby in the three months and 14 days he lived before he was killed by a car in Melbourne's Bourke Street mall, his parents say.

Matthew and Nawwar Bryant say their "most beautiful, loving, happy and perfect little baby" was the light of their lives before the car struck him and injured their two-year-old daughter Zara. Four other people died in the rampage.

"Our beautiful Zara is in a stable condition, however Zachary, our son, did not survive," they say in a statement on Monday night.

"He leaves us with the best three months and 14 days of wonderful memories spent in this world."

"Zac, Mummy and Daddy love you very much, and always will."

They thanked everyone who helped, comforted and grieved with them and asked for privacy to mourn in peace.

Dimitrious Gargasoulas was charged with the murders of five people on Monday.

He is accused of deliberately running them down in Melbourne's lunchtime crowds on Friday, killing Zachary Bryant, three months, Thalia Hakin, 10, Jess Mudie, 22, Matthew Si, 33, and a 25-year-old man.
