IIN to let children be ignorant to preserve their "innocence"?

I personally see it as a way for parents to avoid having to explain topics that they feel their children are too young to understand. Personally, when I asked my Dad where babies came from, he said they came from vaginas and then he pointed to his crotch. My Mom was horrified when I walked up to her and pointed to my crotch and said "Mom, babies come from here!".

Sharing knowledge is great but kids can only understand so much. While I agree with your points, I don't think we need to push the entirety of the reality down their throats. In part, some parents are forced to go with this well, because imagine the shit they would get if their child went to school and told other kids "the tooth fairy isn't real, it's your Mommy and Daddy sneaking into your room at night and putting dollars under your pillow!".

That Is a challenge I'm not looking forward to as a parent - trying to convince my kid that Santa Claus not existing is supposed to be a closely guarded secret. Oi.
