My one year old daughter picked up a typical plastic supermarket grocery bag and I watched her with it briefly before taking it away, as it's common knowledge that kids aren't supposed to have plastic bags due to a risk of suffocation.
After actually seeing a child with a bag, however, I wondered how much of a risk this actually is. I had a very hard time imagining my daughter being able to get her head inside of the bag to such a degree that she would actually suffocate.
I'm [hopefully obviously] not advocating for any controlled experiments here! I just wondered where this common, ingrained warning comes from. How real of a danger is it when children play with plastic bags?
