The exhibition Growing Up in the City at the Museum of Liverpool boasts 25 evocative photographs which capture the life of children over more than 100 years.
As well as a providing a snapshot of those lost days of childhood, the pictures also provide a thought-provoking social history of life in Liverpool through the decades.
The photographs span the period from the 1880s to the 1990s and illustrate just how much life for a child has changed and also how special occasions were marked on the city's streets.
The oldest image dates back to 1887 and is a portrait of Florence, George and Gertie Rollo, who came from Waterloo Park.
The Rollo family lived in a large home in the area called Stone House and had four servants. The picture shows the children dressed up in costumes for a fancy dress ball hosted by the Mayor and Mayoress of Bootle, Alderman and Mrs Howard.
As well as showing children at play, another image reminds us that many youngsters were also sent out to work.
A nervous looking young maid for a well-to-do Liverpool family is captured in a great portrait which is thought to have been taken about 1900.
The exhibition has been put together by Kay Jones, Curator of Urban Community History at the Museum of Liverpool.
Ms Jones painstakingly trawled through hundreds of images from the National Museums Liverpool's collections before deciding on the final 25 for the exhibition.
She said: "This has been a fascinating exhibition to work on.
"Looking through hundreds of different postcards, photographs and glass plate negatives in our collections; it was hard to decide on the final 25 images.
"I chose the ones that really stood out and told the experience of childhood.
"People love seeing old photographs and most people can relate to the same experiences of playing out in the street if they're from Liverpool or anywhere else.
"But, at the same time, the pictures also remind us of how things have changed.
"I didn't want it to be just happy memories, I also wanted to remember the children who had to work throughout their childhood.
"I wanted it to be the good and bad experiences of childhood."
Growing Up in the City is at the Museum of Liverpool until 25 September.

The fashion designer had told Yahoo that casting directors dressed Hadid in a poncho for a fashion show because she was not as thin as the other models.
But he has now clarified his comments and said the story was misleading.
Hilfiger said: "The suggestion that I thought [Hadid] wasn't thin enough upsets me to no end. Gigi is the epitome of perfection."
In the Yahoo interview, Hilfiger referred to a 2015 fashion show in which Hadid wore a poncho which covered most of her body.
Hilfiger said he wanted Hadid to be dressed in something which better showed off her figure, but members of his creative team disagreed.
"Our casting director said, 'She doesn't really fit because you know she's not quite as tall as the other girls, she's not quite as thin,'" Hilfiger originally said.
"So they put a red, white, and blue poncho on her. It covered a lot of her body unfortunately, but it received millions of hits."
Hadid's appearance in the poncho proved hugely popular, and she later went on to collaborate with Hilfiger, launching her own line of clothing for the brand earlier this year.
After Hilfiger's comments sparked criticism, the designer criticised the original story's headline as "misleading".
Speaking to Page Six, Hilfiger said: "The casting people put Gigi in the poncho, and I was not happy.
"I was saying, 'Don't hide her body.' Even though the poncho ended up being the best-selling piece, I was very unhappy."
The designer also released a statement to Entertainment Tonight, in which he said he was "extremely proud" to have Hadid representing his brand.
"Gigi is truly the definition of a 'Tommy Girl' - her magnetic personality is bright, confident and always optimistic," he said.
"I've known her for many years, and am extremely proud to have her as the ambassador of my brand and as a collaborator of our collections.
"Any statement to the contrary is completely false. The headline from the interview with Yahoo was misleading and has since been corrected."
