The sister of the Scots child at the centre of one of the country's oldest missing persons cases says the family is still desperate for answers - 46 years on from his disappearance.
Sandy Davidson disappeared from his grandparents' garden in Bourtreehill, Irvine, on April 23 1976 when he was just three years old.
He had been playing with little sister Donna when he is believed to have chased a family pet dog out of the garden gate.
Despite numerous police searches of the local area and family appeals on national TV, the blonde-haired blue-eyed toddler has never been seen again.
Marking the 46th anniversary of his disappearance, Donna - now 48 - has urged anyone who might know of his fate to get in touch.
Posting on social media, she said: "[It has been] 46 years since we last seen you Sandy - living without you has been tough.
"We all want you home, not knowing where you are is a living nightmare.
"I try every day to try and find memories of you in my head but I've none and that breaks my heart.
"Sandy you're my big brother and I miss you sorely the day you went missing - part of me went with you.
"Love you forever our blue eyed boy."
Sympathy poured in for Donna following her post earlier today from friends and family alike.
Allan Bryant Snr, who is still looking for his son Allan Jr after he was reported missing from Glenrothes in November 2013, commented a red heart emoji, adding: "Thinking of you Donna."
Donna has worked tirelessly to find Sandy for decades.
Last year, she returned to the house where she and her big brother had been playing on the day he vanished, retracing her steps in the hope it might jog someone's memory.
And in January she appeared on an Amazon Music podcast, The Missing, to share the story with a global audience.
She told host Pandora Sykes that being unable to clearly remember Sandy tortured her.
Donna said: "This has been my life. I was only two when Sandy went missing so I've got no living memory of Sandy at all.
"I just need to make my own memories of him, pictures, that's the only memory I've got. I need to imagine a picture to imagine what he looks like.
"How can I not remember him? How can I not just get one memory?"
On the 40th anniversary of his disappearance, Police Scotland launched a renewed appeal for information.
It consulted with experts to generate an image of how Sandy may look at the age of 43.
However, his disappearance remains one of Scotland's oldest unsolved missing persons cases.
Anyone with information on Sandy Davidson or any other missing person is asked to contact police on 101, or the charity Missing People on 116 000.
