I have heard so many stories of parents only turning away for a second and disasters happening, I mean my little cousin pulled a clothes horse down on top of himself and I was watching him. Thank god my instinct was to dive over him so it hit me in the back rather than hitting him in the face, but I've heard of kids accidentally pulling pans of hot water, kids falling into the bath, kids ending up in rivers or pools or getting carried off by rip currents, kids running into roads. I know these are all things more likely to happen to older kids who are walking but it's just so dangerous to leave them unattended, let alone in another room or with your headphones in.
