well yeah, the idea is that you keep a super watchful eye on him while he uses it. Same if your kid is swimming. You don't just go, "Well, the kid is in the pool I guess I'll read a book now" but you go "How long has he been underwater, was it 2 or 3 seconds... 4 seconds is waay too long damnit,*jumps in*" x 50 timer…
