Sorry you required surgery in the first place, Gallus Moll,
and more than sorry about the medication-induced nightmare.
I recall previous posts that have mentioned your dear collie.

Jos, my sincere and startled thank-you's
for a context of which I am ignorant,
since I have never studied child development.
And this is something valid and useful!
Will check this out with my former counselor
-- who changed professions, so can't consult ongoing,
but we are still friends so we have the occasional e-mail exchange.
Thanks again!
