My only male sim to have an alien baby was super paranoid about aliens, got one of them satellites (I got it out of the debug menu) and he set it everyday to prevent abductions. He’s married with 3 kids. One day when I rotated to his house he was being beamed up before he got chance to set the satellite and now has an alien baby boy. His wife seems to love the baby a lot and has bonded with him. One of the siblings has too. My male sim does love him but has found it hard and as his own dad abandoned him and his twin sister he will not do that to his own children including baby alien. My male sim has a very complex background and he is my most interesting sim to play.
