I need help with my 4 year-old daughter not listening..

I think you need to get your daugther tested for ADHD or ADD or even for Aspeger... I know it sounds very hard, but your daugther's behavior may be linked with one of those problems. My son (who is 3) also has some of these problems too, & he was diagnosed with ASD abouth a year ago. Through therapies his behavior has improved a lot... Try to talk to a developmental Dr. or a Neurologist. Your daugther pediatrician may help you to find one of these Drs. If your daugther is already registered in a public school, try to get an evaluation for IEP... Occupational Therapy is a good source to calm down children...
