We are all unique with our own abilities and things we find difficult. People with autism are the same and each child's experience of autism is unique.
Some children with autism may experience their senses differently, which for them might mean that noises can be too loud, smells can be too strong and certain clothes or fabrics can feel itchy and uncomfortable.
Parts of life like making friends, talking with other people, or dealing with a change in plans, can be difficult for children and young people with autism.
Children and young people with autism might have trouble finding the right words, or might copy other words which they have heard on TV shows or in movies, to express themselves.
Children and young people with autism might also use their bodies to show how they are feeling, for example by flapping their hands when they are happy or rocking their bodies when they are upset.
