I love this time of year, this collection of new beginnings. And I like offering parents and teenagers user-friendly back-to-school tips and hacks.

In a busy work living busy lives, we rarely if ever consider the spaces in which we parent. But I’ve learned that those spaces can drive an enormous impact on our parenting, and our collective well-being as a family. Today’s Substack.

I’ve been asked this question countless times - why does my kid bug me so much? The answer is likely closer than you think, and it’s important that you fully understand it. Today’s Substack.

I am hearing a new, nearly universal fear among parents of teenagers and young adults over the past several years: that their child will somehow not survive.

Today’s Substack.
