Activities so far accounted for: pulled along in waggon buttercup in hand; boat ridden; mountain pass passed; swimming pool swum in, outside; bouncy castle bounced on; big (Thomas) tank engine run alongside of; pony gently walked.
Accidents so far logged: pony fallen off, after it trod on father's foot; mountain almost fallen down, after father gave too much credence to the strength of a "dead" branch; cheeks sunburnt.
Calculations calculated? Tyrols generally exceedingly good; fathers need to calibrate risk.
