No matter how many books you read throughout your childhood and adult life, there'll always be a few that stick out.
In celebration of International Children's Book Day, we've rounded up some of The Huffington Post UK's favourite children's books that'll take you on a trip down memory lane through the decades.
The day is celebrated on Hans Christian Andersen's birthday on 2 April every year and aims to inspire a love of reading and bring children's books to the forefront.
You never know, it might even inspire you to pull out a few old books to read to your kids.
