There’s nothing like the deluge of parenting advice when you have a kid. Everyone and their grandmother suddenly knows what’s best, right? And while the majority of people who offer advice are well-intentioned, some of the advice they’re throwing out there is not great. Not BAD, but more past it’s prime. Outdated parenting advice seems to never go away, because if it was good enough for your mom and her mom, it’s good enough for you! Except it’s not. When we know better, we do better. And as far as these 18 pieces of outdated parenting advice go, we definitely know better now.
