I always sow parsnips a pinch at a time. so I am in complete agreement with your daughter. Frankly parsnips can be a bit reluctant to germinate, so I sow 4 or 5 seeds every 9 inches along the row. Then, when they begin to grow, I pull out the weeker looking seedlings just leaving the best looking one. I can't see the point in sowing all along the row, however thinly, when you only need a plant every 9 inches etc. Any seeds sown in the remaining 8 inches are always doomed.
This works for parsnips, turnips, beetroot, kholrabi etc.
