Yes, and let's ban alcohol too because a few people die of alcohol poisoning.
Or you could stop with the hyperbole and look at the facts.
Maybe you could. Hmm?
The facts are that drowning is not common in children over 3 who are left in the bath, that a few seconds is more than likely to be enough time to reach them, and that they are very unlikely to soip under the Walter at that age (unless they delayed physical development).
It's important to know about delayed drowning so you can know what to watch for in the extremely unlikely event of a physically capable and independent child, well used to water, getting into difficulties in their own bathtub.
Just like you should know what to look for in case of a bang to the head leading to concussion, but not make your child wear a helmet all the time.
If baths were so dangerous that children who were at school could not be left unattended for a single second, then it would be foolish to bathe them at all.
They are not that dangerous. Pretending that they are is hyperbole.
