That is one of the most incredibly precious pictures I've seen in a long time!!
The child will let you know when he/she's ready. They'll be like velcro while you're fishing. Offer up a rod (short/light) and let 'em have at it ... spin or fly ... and don't be critical. You'll be surprised how quickly they'll catch on by letting them do their own thing. You'll have a fishing buddy for life!!

Trouts don't live in ugly places.
A friend is not who knows you the longest, but the one who came and never left your side.
Don't look back, we ain't goin' that way.
