This question comes up from time to time: "Does Deciduan provide a prim baby?"
The answer, for the foreseeable future, is "no." And here's why.
Deciduan is meant to facilitate a number of role-playing scenarios, ranging from very innocent to very sexual. E.g., some use it to RP starting a family, but without any associated sexual role-play (i.e., "fade to black" sexual RP). Others are at the other end of the spectrum, and utilize Deciduan in scenarios that would be highly inappropriate for the presence of a prim baby. As such, at the risk of running afoul of LL ToS (and due to the author's own ethics) none is provided by default. Deciduan provides a labor and birth sequence, but only the elements necessary to drive the role play. No additional "visuals" (i.e., prims) are provided.
That said, the interfaces to produce a labor sequence in conjunction with Deciduan are public (see Labor/Birth API). Any developer is welcome to script a prim to work with this sequence and simulate any elements of labor and birth he or she deems appropriate, and I will happily work with developers (time permitting) to assist with use of the API. Developers are, of course, free to sell their Deciduan-compatible products provided they indicate that they are not directly affiliated.
