Is there a sensory issue?

My child has fine motor issues, cannot ride a bike with training wheels at age 5, Is constantly touching things. Hugs constantly and impulsively, does not like tags in his shirts, is afraid to sleep alone,feels like he is being yelled at when he isn't,Is afraid of movie theaters and walks on the balls of his feet. He also does not like trying new activities or sports. It takes a lot of convincing to get him to try and he often does not want to continue with them. One therapist said she thinks it is ADD but the school said that shouldn't be diagnosed until age 8. He is also very curious. Hasn't outgrown the Why stage yet.
