toddlercon
Sexually explicit or sexually suggestive artwork of even younger children (younger than loli and shota) or babies. This is considered a extreme form of lolicon or shotacon.
Safe for work, non sexual images of child in the ages of three to five should not be tagged toddlercon - this is what the toddler tag is for.
If you are not sure whether a post should be tagged as toddlercon, ask in the loli / shota check thread.
