Street Legends Supplemental, in the Slamm-O! profile has the description of the baby. As for Netcat and Slamm-O!'s relationship, that's been a thing through the books since SR4A came out. I think it is the fiction at the start of the matrix chapter? Anyways, in one of the books (forget which one right now) you actually have an example of what happens when a TM experiencing morning sickness is logged on via VR to a message board.
