You can get bones from harvesting dead sharks or dead residents. To make babies, your survivors need to be in good state (not hungry, thirsty or sleepy) and they have to be idle for a while.

To describe the exact conditions of making babies is really a hard job.
First of all, survivors should be satisfied.
And, they should be idle for a while.
Meanwhile, there must be enough room, such as more than 30 pieces of rafts.
