A best friend of Cleo Smith has penned a heartfelt letter to the missing four-year-old.
Six days after she disappeared from her family tent at the Blowholes campsite north of Carnarvon in Western Australia, Cleo's little friends are starting to ask questions about where she is.
'Dear Cleo, can you please come back for a little while and come to my nan's?' one letter written by one of her friends reads.
'I miss you and I hope you are alright.'
The letter is accompanied with a drawing the little friend made of two girls, presumably she and Cleo, standing side by side with smiles on their faces.

The little girl's mum, who has been actively sharing Cleo's missing person poster and photos online to raise awareness, said her daughter was desperate to write her friend a letter.
'We all just want you home safe and sound baby girl,' the woman added.
Friends and family of Cleo's mum, Ellie Smith, have been pillars of support since the four-year-old's disappearance, vouching for her character online and doing everything they can to alert the public.
Ms Smith made a harrowing statement about 6.20am on Thursday morning - exactly six days after she discovered her eldest daughter was missing.
'I miss you. I love you. Please come home to me,' the mother-of-two said.
Cleo, along with her mum, stepdad Jake Gliddon and baby sister Isla had only arrived for the weekend getaway hours prior
Cleo disappeared from the family tent between 1.30am and 6am on Saturday.
She, along with her mum, stepdad Jake Gliddon and baby sister Isla had only arrived for the weekend getaway hours prior.
Ms Smith has issued several pleas for her daughter's safe return since she realised Cleo was missing, the first on her Facebook page on Sunday and the second to the media on Tuesday.
Early on Thursday morning, she spoke publicly again to share the missing child poster that was created by strangers and distributed widely across the nation.
The poster illustrates the red and grey sleeping bag that disappeared with Cleo along with a number to call police.
Cleo's family have told detectives they will remain at the campsite, hopeful the little girl will wander back in
She also shared a fresh picture of Cleo enjoying a Cornetto ice-cream in a leopard print jumpsuit. Her pink scooter was visible in the background.
'My sweet girl, come home to me,' Ms Smith captioned the photo.
Cleo's family have told detectives they will remain at the campsite, hopeful the little girl will wander back in.
But detectives fear with every passing hour, there is less of a chance they'll find Cleo alive - or nearby.
'Whilst time is not on our side... there have been instances in the past where even small children lost in remote areas still being found safe and well,' acting Deputy Police Commissioner Darryl Gaunt said.
'There's been some rain that gives us hope that there's water on the ground, those type of things which, you know, we take all of these things on as a positive, and we keep searching with every bit of energy that we have.'
