More common in children and teenagers.
Showing 8 oddities.
This tag marks entries that are more common in children and teenagers than in adults. The palmar grasp reflex, geometric nightmares, and Alice in Wonderland syndrome all appear mostly, or only, in younger people.
The tag exists for a parent, or a reader looking back, wondering whether something they remember from childhood was normal. In most cases here, it was.
This list will tell you at what age each entry typically appears and typically fades. It will not tell you whether a specific child's experience needs medical attention. When an entry could be a warning sign in a particular age group, that detail sits in the entry itself, not in this tag.
