While there are things that I hope we seriously never resurrect from the '80s and '90s (scrunchies, Caillou, and New Coke, I'm looking at you), there are some 90's parenting decisions we need to bring back, like, now. Clearly, every generation of parents has made their fair share of mistakes. I mean, I love my mom, but she didn't exactly have an open talk with me about my sexuality when I hit puberty. That said, there are a lot of techniques that worked better than the decisions we make now, collectively, as parents.
I think it's incredibly important to not let the pendulum swing back too far in the other direction, once a generation has gone too far on way or the other, but actually aim that pendulum so that it hits the mark. For example, condemning spanking doesn't not have to mean that you don't offer your children any form of boundaries or discipline whatsoever.
Sometimes parents get it right, after looking at past generations and how they parented, then tweaking their own parenting style to accommodate choices and decisions they feel comfortable making, only to get condemned or steered away from a particular way of raising kids. Other times a "fad" parenting technique will cause otherwise confident parents, to second guess themselves. And then, of course, technology comes into play and changes how we parent, without us even realizing it. Seriously, how in the world can you, first and foremost, confidently decide how you want to parent and then, well, stay confident?
