ELI5: Why do babies going through a severe stranger anxiety don't seem to be bothered by stranger kids? At what age/height/weight/other factors do they internally differentiate between kids and adults?

Simple, it’s the human instinct to be alerted in front of threat. Babies constantly learn about the world around them, and to realize which are potential threats. In the baby’s mind, adults only mean larger animals; thus this alert system kicks in. Some babies still afraid of other kids, however most of the time the kids’ mind see those as mangable threats, so the system signals the babies to chill out.
