They avoid certain numbers, colors, or words they think are 'unlucky'
Your child refuses to sit in seat 13, won't wear red because it's a "bad color," avoids saying certain words, or insists on only even (or odd) numbers. These avoidances have started to affect daily life — they won't eat four chicken nuggets, won't write certain numbers in math class, or become upset when an "unlucky" thing appears unexpectedly.
What's Happening (The OCD Cycle)
Avoidance of specific numbers, colors, or words is a form of magical thinking where OCD has tagged certain symbols as dangerous. Your child's brain has created an association — often arbitrary — between a number, color, or word and something bad happening. The number 13 doesn't carry actual danger, but OCD has labeled it as threatening, and the anxiety that arises when your child encounters it feels identical to the anxiety of a real threat.
The compulsion in this case is avoidance itself. By steering clear of the "unlucky" thing, your child never experiences the feared consequence (which wouldn't happen anyway) and never learns that the association is false. Every successful avoidance reinforces OCD's claim: "You avoided the number 4, and nothing bad happened. Good thing you avoided it!" The avoidance feels protective but is actually maintaining the fear.
This pattern often starts small — one number, one color — and expands. OCD is creative: once it establishes that some things are unlucky, it begins finding more things to tag. A child who starts by avoiding the number 7 may eventually also avoid 17, 27, 70, and any sum that equals 7. Colors, words, names, and even places can be drawn into the web. The world shrinks as the list of "dangerous" things grows.
How This Looks by Age
Your young child has designated certain numbers as 'bad' or 'scary.' They refuse to use that many of something (won't eat 4 crackers, won't use the 4th crayon), freak out if they notice the number on a sign or clock, and may avoid pages in books. They also may have 'lucky' colors and 'unlucky' colors, refusing to wear certain colors or use certain toys. The rules seem arbitrary but are absolutely rigid.
You might say:
“I know you don't like the number 4 right now because the Worry Monster said it's unlucky. But numbers are just numbers -- they can't be lucky or unlucky. Look, I'm going to give you 4 crackers and we're both going to be totally fine. The Worry Monster might say otherwise, but we've caught the Worry Monster fibbing before, haven't we?”
Your child has an elaborate system of lucky and unlucky numbers, colors, and words. They avoid certain channels, won't sit in specific seats, and may refuse to answer question number 13 on a test. They cross out 'unlucky' words in books, choose clothes based on 'lucky' colors, and organize their day to avoid 'bad' numbers. The system is expanding and consuming more mental energy. They feel controlled by it but can't explain the logic to others.
You might say:
“I know OCD has a list of numbers and colors that feel dangerous. I want to try something with you: let's use the 'unlucky' number on purpose today. We'll set the volume to 13, or eat 6 carrot sticks, or whatever the OCD says is bad. Then we'll check: did anything bad happen? I'm going to do it with you. We're building evidence that numbers don't have magical power.”
Your teen's number and color avoidance has become internalized and sophisticated. They adjust volume levels to 'safe' numbers, set alarms at specific times, and organize their social media to avoid bad numbers. They may avoid certain friends whose phone numbers contain unlucky digits. They know it's irrational and feel deeply embarrassed, but the anxiety of violating the rules feels worse than the inconvenience of following them.
You might say:
“I want to talk about the number thing because I can see it's getting bigger. OCD has convinced you that certain numbers are dangerous, and every time you avoid them, OCD gets stronger. What if we picked the least scary 'unlucky' number and you used it on purpose this week? Set your alarm for that number, eat that many bites of something. Let's collect data on what actually happens versus what OCD says will happen.”
What NOT to Do
Avoiding the triggers alongside your child
When you skip aisle 13 at the grocery store or serve five nuggets instead of four, you're validating OCD's rules. It feels like accommodation — and it is. The more the family avoids the 'unlucky' things, the more real they become in everyone's mind.
Telling them superstitions are silly or childish
Your child doesn't fully believe in the superstition the way they believe the sky is blue. They know it doesn't make rational sense. The problem is that the anxiety is real even though the belief is irrational. Calling it silly invalidates a feeling they can't control and makes them less likely to talk to you about it.
Overexplaining why numbers and colors can't hurt them
Logical explanations are reassurance in disguise. Your child's rational brain already knows that the number 4 isn't dangerous. The anxious part of their brain doesn't care about logic — it cares about the feeling. Explaining doesn't reach the part of the brain where the problem lives.
What to Try Instead
Unlucky Thing Exposure — Start Small
- 1.Make a list of all the avoided numbers, colors, or words, ranked by how much anxiety each one causes (1–10).
- 2.Pick the least distressing one to start with — maybe a mildly unlucky color or a number that's only avoided in certain contexts.
- 3.Introduce small, brief exposures: write the number, say the word, wear something in the color for 10 minutes.
- 4.Don't add reassurance: don't say 'see, nothing happened.' Just move on to normal activities.
- 5.Repeat daily until the anxiety around that trigger drops to a 1 or 2, then move to the next item.
You might say:
“Let's make a list of all the things OCD says are unlucky. We'll rank them from 'a little uncomfortable' to 'really scary.' We're going to start with the easiest one. OCD says the number 9 is bad? Okay — let's write the number 9 right here on this paper. Look at that: we wrote it. OCD is probably not happy. Let's leave it there and go make a snack.”
Lucky vs. Unlucky Experiment
- 1.Frame this as a science experiment: 'We're going to test whether lucky and unlucky things actually make a difference.'
- 2.On one day, have your child do everything the 'lucky' way — use safe numbers, avoid bad colors, say only good words.
- 3.On the next day, deliberately include one or two 'unlucky' things.
- 4.At the end of each day, compare: 'How was your day? Did anything actually bad happen on the unlucky day versus the lucky day?'
- 5.Repeat over several weeks, building a data set that shows no correlation between the superstitions and actual events.
You might say:
“We're going to be scientists this week. Monday and Wednesday, we'll do things OCD's way — all safe numbers and colors. Tuesday and Thursday, we'll include some 'unlucky' things on purpose. At the end of each day, we'll rate how the day actually went. My prediction is that the lucky days and unlucky days will be about the same. Let's find out if I'm right.”
Flooding the Unlucky Thing
- 1.Choose one 'unlucky' number, color, or word — preferably one that's been causing moderate distress.
- 2.Surround your child with it for a planned period: write it on their hand, put the color everywhere, say the word repeatedly.
- 3.The goal is saturation — making the stimulus so ever-present that the anxiety response can't sustain itself.
- 4.Stay with your child during the exposure. Don't minimize, don't reassure. Just be present.
- 5.Continue until the anxiety noticeably drops (this may take 30–60 minutes the first time, and gets shorter with repetition).
You might say:
“Today we're going to take the number 4 — which OCD says is unlucky — and put it everywhere. We're going to write it on your hand, put sticky notes with 4 on your mirror, eat four crackers, do four jumping jacks. We're going to fill the day with 4s. OCD is going to freak out at first. That's okay. We're going to prove that the number 4 is just a number. By tonight, I think OCD will be bored of trying to scare you with it.”
When It Gets Tough
When your child deliberately encounters an "unlucky" number, color, or word, the anxiety can spike quickly and feel disproportionate to the situation. They may become tearful, clingy, or irritable. They might try to secretly "undo" the exposure through a mental ritual — counting to a safe number in their head, or mentally repeating a protective phrase. This is normal and expected. The extinction burst with avoidance-based OCD often includes an increase in other rituals as OCD tries to compensate for the one being challenged. Don't chase every new ritual — stay focused on the current exposure target. Most children with avoidance-type magical thinking respond well to exposure within one to two weeks per trigger, especially at the milder end of the severity spectrum. As they build evidence that the unlucky things don't cause bad outcomes, their confidence grows and subsequent exposures become easier.
When to Get Professional Help
Consider consulting a specialist if:
- •The list of 'unlucky' things is growing and beginning to significantly limit what your child can do (refusing certain school subjects, avoiding entire locations)
- •Your child is developing elaborate mental rituals to counteract accidental exposure to unlucky things
- •The avoidance is causing social problems — refusing to attend parties, play sports with certain jersey numbers, or eat at restaurants
- •Your child is becoming increasingly rigid and distressed, even when you're actively working on exposures together
- •They've started attributing real-life negative events (a bad grade, a friend being sick) to having encountered an 'unlucky' thing, reinforcing the magical connection
