There are plenty of people who work with children yet may not have children: teachers, child care workers, medical doctors, psychologists, social workers, etc.. In each case, we see children in contexts that parents do not. In some of those professions, we may even see individual children more than their parents do. Perhaps it is best to avoid deprioritizing people simply because they don't meet an arbitrary criteria.

(I've had people scream at me because I am not a parent. When they found out what I do professionally, they were immediately humbled.)
