Helping your young acting hopeful prepare for a successful acting career can be an incredibly rewarding experience for the parent. All parents like seeing their children being creative, expressing themselves, and, most importantly, having fun.
It should be stated, however, that forcing a child to participate in any pursuit they don't like is not just counterproductive but harmful to the child. Your role, as the acting hopeful's parent, is to caringly nurture your children's expressed interests and not force them into a pursuit in order to live vicariously through them. One would have to be born under a rock to have missed some of the more public examples of what can happen when children are forced into an acting career they never wanted.
