There are rare, but more serious causes of this behavior such as Autism Spectrum Disorder (ASD). However, children with ASD have a host of other difficulties besides self-harming behaviors such as prolonged tantrums that can last an hour or more, delayed language development and difficulty with social interaction and recognizing facial expressions. They also tend to have rigid adherence to patterns or routines and severe tactile sensitivity. If she has any of these issues, please talk to your pediatrician about getting an evaluation for ASD.
