Sensory processing disorder

What would be the signs of sensory processing disorder in a 3 year old? My 3 year old is very picky eater, loves to jump stomp stim from time to time, talks alot but is still working on clear words and more sentences! Doesnt like sunlight when we are in the car and does okay with some loud noises but not all of them. Bounce legs when we are sitting eating or when they are watching tv. They try to communicate and have pretty good social skills for the most part!
