I've seen many questions addressing when Time Lords can regenerate, and a few on what they regenerate into, but all address adults.
There is no question that Time Lords have children - we see both River and the Master as a child, and there were 2.47 billion others on Gallifrey at the time of its 'destruction'. But are all those children actual children? Could some be on their 6th regeneration? Or even 8th or 9th? Can Time Lords Regenerate into the appearance of children?
