The Fourth of July is one of my family’s favorite holidays. It’s an all-day event full of festivities, fireworks, and our favorite people. But don’t get it twisted, it can be the ultimate endurance test for kids and that all has to do with their sensory threshold.

Sensory Threshold is the amount of sensory input required for a person’s nervous system to register and respond to it. This concept is key to understanding how individuals process sensory information, especially in frameworks like Dunn’s Model of Sensory Processing. Developed by occupational therapist Dr. Winnie Dunn, it addresses sensory modulation (how the brain regulates sensory information) by outlining how sensory thresholds and behavioral responses interact across four sensory processing patterns:  

• Sensory seeking (high threshold, active response) – seem to never get enough input no matter how long, how intense, or how much is given; may appear excitable or lack any consideration for safety
• Sensory avoiding (low threshold, active response) – will actively avoid overwhelming input by any means necessary; may withdraw, attempt to control their environment, or have an emotional outburst
• Sensory sensitivity (low threshold, passive response) – notices everything, resulting in distractibility
• Low registration (high threshold, passive response) – requires more input or time to register and respond to stimuli than others; may appear withdrawn or uninterested

OTs use this knowledge to better understand behaviors and determine strategies to help people regulate their sensory experiences, especially when it comes to intense sensory celebrations like the 4^th. While those with high sensory thresholds may find the smorgasbord of sensory input exciting and fun, those with lower thresholds may feel like this day is a never-ending nightmare. Things to consider:

• Sound – loud noises from fireworks, parades, live music
• Sight – bright flashes and visual chaos from festivities
• Smell – smell of various kinds of food, burning gunpowder from fireworks
• Touch – crowds and unexpected physical contact, exposure to different textures for an extended period (concrete, grass, sand, water, sunscreen, etc.)
• Taste – different flavors that may be too sweet, salty, tangy, or spicy
• Interoception – change in routine, excessive heat and limited shade, hunger, thirst, overall exhaustion
• Proprioception – reduced access to parents
• Vestibular – bounce houses, slides, high energy pool games

All these simultaneous sensations can result in a sensory overload, leading to anxiety and emotional meltdowns. As parents, we know that prior proper planning goes a long way to prevent situations from going sideways. So, here are some strategies to lessen the sensory overwhelm.

• Create a visual schedule, walking your child through the day’s events so they know what to expect and help them mentally prepare. It also is a good opportunity to discuss any fears or apprehension they may have and ways to address it.
  
  
• Sift through photos of people they may encounter at a family event so people they don’t see as often become more familiar.
  
  
• Share with them to what they’ll encounter (through books, YouTube videos, personal stories) to help build familiarity and reduce any uncertainty. You can also gradually increase the volume to videos of fireworks or parades to help desensitize their ears.
  
  
• Pack noise-cancelling headphones/earplugs. Also, don’t forget sunglasses, sunscreen, water bottle, towels, and a change of clothes (if waterplay is involved). For infant and toddler parents, bring more diapers, bottles, and swim diapers than you think you’ll need. The change in schedule will impact pooping and feeding times.
  
  
• Bring familiar foods. While there will certainly be opportunities for your child to try new things, it may be best to pack their favorite snacks or food items to prevent a meltdown. Make sure you are building in snack time and hydration breaks throughout the day. Also, avoid food that has been sitting out in the heat (a common holiday oversight).
  
  
• Create a calm space where your kid can retreat to when things become too much. If you’re at a relative/friend’s house, ask there’s a room that can be used for your child to nap or relax if they’re overwhelmed. For younger kids, a pop-up tent or pack-and-play will do the trick. A nap may also just be a good idea since it doesn’t get dark until 9pm and fireworks make for a late night.
  
  
• Pack a calm-down kit to help them regulate.  
  
  
• Avoid the use of electronics (tablets) as it will only add to their visual processing overload.
  
  
• Stick with comfy clothes to reduce tactile sensitivity and irritation. Soft, tag-free, breathable fabrics are best. Bring a second bathing suit so they aren’t running around all day in wet clothing.
  
  
• Allow for an early exit if the festivities become too much for your kid to handle. Come up with a code word, hand signal, or gesture to politely (and discreetly) leave a party.
  
  
• Watch fireworks from a distance to reduce the sound, brightness, and the crowd of people.
  
  
• Remember we are in a heat wave! Wear hats, reduce your sun exposure, drink water and Gatorade, stay in the shade when you can. Bring a pop-up tent if you can. If your kid is getting dizzy or having trouble breathing, please take it seriously.
  
  
• For you adults, also watch your alcohol intake. The Fourth can be an all-day event and by the end of the day, you may not be at your sharpest. Make sure you are drinking water and don’t fall asleep in the sun.

With a little prep, a supportive setting, and attentiveness to your child’s individual needs, you can make the day both joyful and memorable for the whole family. Remember that every child is different, so discover what feels right for yours and celebrate in a way that respects and supports their unique sensory experience.
