Most kids with mild sensory problems and no other issues do just fine learning and socializing at school with a bit of understanding, extra support, a sensory diet, and a few simple accommodations. You may be able to work this out informally with your child’s school. However, a child with sensory processing disorder (SPD) may need more help to thrive in the classroom and elsewhere at school (the cafeteria, gym, art class, etc.).
