apical trills

[Brian MacWhinney]

First possibly lost message:

Has anyone any information on first language acquisition of apical trills
(e.g. in languages such as Italian, Spanish etc etc). I'm particulary
interested in age by when these become established AND commonest
substitutions for the trills before they're established.

Please reply directly to me: I'll post a summary if there's sufficient
information.
