What this tends to mean is that having to actively monitor small children to make sure that they don't drink drain cleaner or crack their skulls open is seen as a means by which children who actually do understand what the poison control symbols mean and what gravity is can pretend that they don't so that they can deny the mother they hate free time.
This would be bad enough were it not for the general premise of the strip being Elly thinking to herself "HUM!!! The children survived what all of those mean picky-faces who hate me and tell me I can do better than what's right call negligence; therefore, my ignoring them was the right thing to do." What this means is that we can expect Katie and Lane to be the targets of Lynnsights about denying childhood for years to come. Given that this will accompany Lynnsights in which Elly will be "vindicated" for making the absurd assumptions she does about why children do dumb things, we're in for a lot of bad parenting being presented as good.
