Sample. Observe. Record.    The child needs to sample a variety of activities and as their parent you need to be open and observant. Try to be as non-biased towards activities and you can. Watch them and record your observations about how they respond to these activities.   Once you find the right one or two activities it comes down to you being passionate as the parent. Be as involved and helpful as you can. Ask the instructor what else you can do to help. Be there for the events and stay to help out the community. Show your passion and self-drive as a parent and your child will be more likely to mimic that behavior. Nothing can be certain, but this will increase the likelihood of the outcome you imply from your question.   The tortoise always wins, Julian
