Does a seven-year-old have enough sense not to sew his finger?

Does it even matter, whether he has enough sense? Is it best for him to learn and experiment and make and play regardless of the small dangers to his body, regardless of the fears of his mother?

I suspect I simply have to allow him to live and learn and hold my breath. Probably deep breathing would be better still. I remember the freedom I was given, as a child, but I can’t remember my age. Was it at seven or at eleven that I sewed my own halloween costumes?
