With my daughter nearing sleepover age, I didn't know how to approach other dads about their guns and how safe they are. So I asked.

Three percent of full-term boys (and 30 percent of premature boys) are born with an undescended testicle. One such boy is my son.

What I love about this game for me is that it gives me insight into how my kid sees the world. What does she remember, what upsets her, what inspires fear?

There's Tinder for singles. Peanut for moms. But nothing for lonely dads looking to connect with like-minded fathers. What gives?
