With pre-verbal children we have to be creative and come up with concrete ways of conveying information about dangers, rather than just giving explicit explanations. (I suggest both.)
It is far safer to show children potential dangers and how to handle them safely, than it is simply to rely on them never interacting with such dangers. Even if you yourself keep all the dangerous items and chemicals locked up, there will come a day when your child is somewhere else, where that is not the case, and then your child is potentially navigating dangerous things with no knowledge of how to do so safely. Taking our children seriously is so much safer than the alternative.
How would you feel if your partner took it upon himself to ‘protect’ you from something you do not want to be protected from, or he rode roughshod over your wishes with respect to the protection he was offering? It is dishonest to call something ‘protection’ when it is against the will of the person being protected. It is a parent’s responsibility to protect children from harm as perceived by the child.
Sometimes you can explain in terms of your experience; but not when it comes to drinking bleach, presumably!
Children’s lives are their own, and they are far more competent than many parents think they are.
What if [insert feared disastrous outcome here] happens as a result of taking my children seriously instead of coercing them?
American children should be prepared for the playmate who reaches into his parents’ drawer and comes out with a loaded gun
Reason keeps a child safe because the child has the correct theory (that the stuff is dangerous); coercion is risky because the child’s theory is not based on the reality of the substance, but upon the possible punishment for an infringement of the parental rule.
