I'm trying to figure out if the symptoms my 3.5 year old son exhibits are OCD related or just "normal" for a 3-4 year old. I understand that all 3-4 year olds have tantrums and want things to be "just right." But our son seems to do this to an extreme. As an example, he won't go up or down our stairs without counting at each step. And in the morning our entire family has to walk down the stairs at the same time. When someone is leaving the house, they have to honk 3 times. If these things don't happen, it is a ~30+ minute meltdown. Are these just normal for a child his age? Or worth digging deeper?
On a side note, my wife has similar symptoms, mainly dealing with cleanliness and germs/dirt. She will freak out over any dirt in the house, dirty feet getting into bed, is worried about germs everywhere, has a really tough time in hotels, etc. Whenever we travel she gets migraines, and I'm 95% positive this comes from stress/anxiety from travel. If we fly, she's worried about germs on planes. Even if we drive somewhere, there is always some added stress that leads to a migraine. She isn't concerned about him and thinks it is normal for him. I'm a little worried that her perception of "normal" is skewed a little. As an example, to try to get around his counting issue going up stairs, she now has him counting in his head instead of out loud. I'm worried that we are reinforcing the behavior and encouraging him to do more rituals like counting internally.
Thoughts?
