Curious---Tad left or right handed?

[AussieMick]

In Victorian Britain there was a very strong impetus to force (literally) children to use their right hand. The damage done doesnt bear thinking about. Bed-wetting and stuttering were the minor issues caused.

The below site describes problems that Tad may or may not have had, including a partial cleft palate, dental abnormalities, and enlarged adenoids. Problems in language development seem to have been issue too, although these could have been those that are often related to some boys even these days.
