But the daily task of washing Mya's bloodied bed sheets is over for Dickens after last Friday's surgery successfully removed the entangled blood vessels.
All her teeth were removed during the surgery as well.
"We're so happy, she's not going to be bleeding or have the irritation the AVM causes," Dickens said.
Instead the close pair were excitedly thinking about the future activities the "strong little girl" could fearlessly enjoy, which included her favourite: playing games outside with school friends and family.
The biggest highlight, Dickens said, was the reduced swelling in Mya's cheek.
"We will be out somewhere and people will stare at her, thinking she's being hurt because of the bruising and her swollen cheek. I just have to explain to them it's her medical condition. "
Mya's inner-strength throughout her medical journey blew Dickens away.
"Last time the doctors said the surgery didn't work, Mya patted me on the back and said, 'Mum, it's going to be alright'. I should be her rock but she is mine."
Dickens, whose work life became limited because of the around-the-clock care and appointments her "princess" required, has a Givealittle page to help continue Mya's treatment, which may include dentures.
