There are some similarities between babies and Companion Cubes. For starters, area and state regulations do not allow the Companion Cube to remain alone and companionless. Babies are also not allowed to be left alone and companionless. Companion Cubes cannot speak and if they do, you should disregard their advice. Much the same could be said about babies. After all, even if they do speak, are you gonna trust someone with so little life experience? Also, you should not throw your baby into a furnace, no matter what GLaDOS says.
