This applies to both Feature and Original Characters. Sometimes people may want their characters to have children. In order to do so, it would require the approval of both Theme and TP staff. Please keep in mind that no one may apply for an Original Character who is related to a Feature Character, such as siblings or children. But if you wish to have a child IC, submit a +request to gain approval. Staff will have to approve the characters having a child since it is such a major event that could effect future players of Feature Characters.
Original Characters fall under the same rules due to the fact that traits would need to be updated to reflect the new changes in the character's life.
To be honest, this could potentially be a difficult proposal to get passed so do not be surprised if there is a rejection, particularly for Feature Characters. It is not necessarily impossible but many things will be considered including how long the player has been with the game as the character in question.
