This does seem to bring about some conflict, with parenting ideologies. Some say they have to learn. Others say we need to protected our children at all costs.
Neither philosophy is full proof. If you let them learn on their own: An example I think would help here....
Ex. You tell your child no! no! no! when pulling on chords and continuously pulling out the plug protectors and insisting on playing with the receptacle. She heres no, but is still too young to understand the consequences. One day you here POP the breaker trips and your little one has a permanent Mohawk.
Ex2. You take every precaution to guard her from this danger, and when she gets older unfortunately she does not learn the dangers these things have. So she grows up with no appreciation the danger they pose, therefore has no respect for them.
Which could also leave her with a Mohawk for the rest of her life.
So whats everyone take?
