Eiche can hold his head up. His grip is strong, and he can use either one or two hands to hold things (including people's hair!). When he returned from New Mexico, we raised his saucer jumper by a notch (either he's grown, or can stand up better, or both). He has more control over his voice, and sometimes seems to get loud "just for practice" rather than as a complaint.
He now has two teeth in the center of his lower jaw.
