Lilia died from a suspected stab wound in Boston, Lincolnshire, in July.
Pictures released by Lilia's mum, Lina, and stepdad, Aurelijus, show her dressed in a blue bubble suit, at a bike show in Boston, playing in the kitchen, at an aquarium, and at a dance competition sharing a hug with her sister.
The family are now fundraising for a statue to be installed in Boston, close to the street where she lost her life.
In a statement issued through Lincolnshire Police, Lilia’s mum Lina said: “There are so many things we could say, but we are not going to talk a lot about who she was and share those stories from our home; they are ours and we want to keep them for us.

“She was cheeky; quiet in one way and then other ways she wasn’t.
“She always tried to make fun.
“You find yourself looking for her everywhere. We had four corners and now one is gone.”
Lilia attended Boston Pioneers Academy and was previously a pupil at Carlton Road Academy.
The family say they want to keep some of their memories private.
Arrangements for Lilia's funeral have not yet been made.
