Is it up to us as parents to choose for our children the paths that they will follow?
No it isn't but it is our job to guide them in the principles that we think are right (getting OT). But we are talking about big extremes here. We aren't talking about letting our son or daughter participate in a sport. We are talking about separating family members and putting our child through extreme training regimes. Is splitting up the family for long periods worth what is ultimately a career in entertainment? I personally don't think so. What will they have to fall back on if they don't make it, or when their career is over (as many sports are short-lived careers)?
But I would be more inclined to reconsider if the activity had more of a altruistic effect. But I don't think I would personally consider a long-term separation.
