Our adult, (not always) sophisticated sense of humour might involve laughing at Epic-Cat-Fails videos on the internet or at very bad puns, but do you remember that period when the re-appearance of mum’s face with a “peek-a-boo” was the best joke in the world? Probably not, but it was a fascinating one! Babies start laughing before they start to crawl, walk or talk and, before long, they start producing their very own non-verbal jokes to make people around them laugh. They start smiling at their first month and they laugh for the first time around 4-5 months of age, while they begin a humorous interaction by their 7-8 months. This very early adorable behaviour is proposedly connected to general cognitive development, as well as to the quality of the bond between infants and their caregivers – thus researchers have tried to describe the different ways infants joke and, mainly, what are the things they find amusing.
