Red Flags of Sensory Processing Difficulties in Young Children Starting School
Starting preschool or kindergarten is a big transition for children and families. New routines, noisy classrooms, and structured expectations can shine a light on challenges that may have been less noticeable at home. For some children, difficulties with sensory processing may make this transition especially tough. Occupational therapy can play a key role in supporting these children so they can participate fully in learning and play.
What Is Sensory Processing?
Sensory processing is how the brain receives and organizes information from the senses (sight, sound, touch, taste, smell, movement, and body awareness). Most children can adjust to sensory input throughout the day. For kids with sensory processing challenges, everyday experiences can feel overwhelming, confusing, or even distressing.
Red Flags to Watch For in Pre-K and Kindergarten
Every child develops differently, but here are some common signs that sensory processing difficulties may be impacting your child:
1. Over-Responsiveness (Sensitive to Sensory Input)
Covers ears or cries with everyday noises (classroom buzz, hand dryers, fire drills).
Says that they don’t want to go to school because it’s loud.
Avoids and becomes distressed with messy play (paint, glue, sand) or becomes distressed with unexpected touch.
2. Under-Responsiveness (Low Awareness of Sensory Input)
Seems unaware of their name being called or doesn’t notice when bumped by peers.
Appears unusually tired, “in their own world,” or slow to respond.
Seeks strong input—like leaning heavily on objects or bumping into people—without realizing it.
3. Sensory Seeking
Constantly moving, climbing, spinning, or crashing into things (more than same-aged peers).
Seeks out loud noises, bright colors, or bright lights.
Has difficulty sitting for circle time or structured activities (more than same-aged peers).
For this point, I feel like I have to put a disclaimer in here that it might be circle time that is the root of the problem, and not your child’s sensory system. If circle time is longer than 10-15 minutes for preK and longer than 20 minutes for K and doesn’t have an active participation component, then it’s very possible your school has expectations that are not developmentally appropriate.
4. Motor and Coordination Challenges
Struggles with holding crayons, using scissors independently (K+), or managing playground equipment.
Trips, bumps, or falls more often than peers.
Avoids new play equipment, swings, or gross motor activities.
5. Impact on Behavior and Learning
Meltdowns during transitions or in noisy environments.
Difficulty following multi-step directions (i.e., go grab a book and sit on the rug).
Trouble engaging in group play or maintaining attention.
Why Early Support Matters
When sensory challenges go unaddressed, children may struggle with confidence, behavior, and social skills. Early support through occupational therapy can help children develop strategies to regulate their sensory systems, build motor skills, and fully participate in classroom routines.
What Parents Can Do
Talk to your child’s teacher if you notice consistent struggles with transitions, attention, or self-regulation.
Seek an occupational therapy evaluation—OTs are trained to administer assessments focusing on sensory processing and provide individualized strategies that aren’t just “sensory for sensory sake.”
Support at home: predictable routines, calming sensory activities (like swinging, jumping, or deep pressure hugs), and opportunities for play with different textures might help.
When to Seek Help
If your child’s sensory responses are significantly interfering with learning, play, or daily routines, it may be time to connect with an occupational therapist. Early support can make the school transition smoother and help your child thrive.
