Many children have obsessions and compulsions. They can be a normal part of children’s development. For example, your child might go through a stage of wanting his bedtime ritual to be exactly the same every night.
Obsessions are thoughts, images or urges that a child doesn’t want but can’t get out of her head. When a child has these thoughts, she might also feel very anxious or fearful.
Some examples of obsessions might be:
imagining loved ones getting hurt
being scared of getting sick from touching dirty handles
feeling that something terrible will happen if your books aren’t in the right order.
