Highly Sensitive Children: Is there a sensory piece of the puzzle?

I always thought Samantha was just more ‘intense’ than other children. Her reactions to nearly everything were incredibly strong. She threw massive tantrums at least multiple times a day over things such as having to sit in her car seat or accidentally getting water in her eyes during bath time. People would tell me tantrums were “normal,” but I felt it wasn’t normal to be having such intense tantrums so many times each day. She was incredibly impulsive. She also seemed to both seek physical input (for example, by climbing on others) while also protesting intensely any physical touch that she didn’t like (for example, an adult restraining her from an unsafe situation). She would melt down if someone else did something she wanted to do like flush the toilet, push a button, or turn on the faucet to wash hands, and she often didn’t “recover” for several minutes, even an hour at times. She also had a hard time listening to and following directions, so things like getting her dressed were often very difficult. I felt completely overwhelmed and lost.
 

I have found in my work that children who are highly sensitive from an emotional standpoint are also likely to be more sensitive to sensory input—to some degree. They experience sights, sounds, tastes, smells and/or textures more intensely. They may become afraid of public bathrooms because the flusher is too jarring and loud. They may reject foods that have strong tastes and smells. They may find bright lights uncomfortable.
