Mr. Baker: About what age does a Changeling child start to develop their changeling abilities, or does it start to exhibit some component of that when they are born?
Like a young Changeling making itself look like a Halfling or so. #DnD #dnd5e #Eberron

A changeling manifests the shapeshifting ability at about one year of age. Part of the point is that changelings born to members of other species match the apparent species of the mother for the first year, ensuring they won’t be abandoned. More here: https://t.co/HA2dJrm9Wx
