(CNN)"Oh, puberty," laments Amanda Rodriguez, a mom of three boys, ages 8, 11 and 14.
I had asked her about that moment when she knew that her older boys definitely needed to start wearing deodorant.
"All of the smelly fun a girl can handle," the Frederick, Maryland, mom joked, noting how the body odor is just beginning with her middle son.
"And then, all of a sudden you're choking on Axe body spray and scraping gobs of hair gel off your bathroom sink," she jokes. "The switch is just flipped (probably by some girl, gah!) and the 'I don't-want-to-stink-light' is officially on. Parenting goal achieved."
She started to talk with her boys about body changes in the fourth grade by giving them a book about boys' bodies. She let them read it independently and then discusses it with them from time to time. "We try to focus on the positives, that they are going to get taller and stronger, and then we weave in some hygiene lessons as they come up," she said.
Flick Wilson, the mom of twin teens, says she's tried to be as open with her kids as possible, about everything from body changes to body hair to deepening voices, which is quite a contrast from the way she grew up.
"I think that as much as I loved my Catholic school upbringing, it was never a conversation you had, whether it was body changes or sexuality or you name it," she said. "And so, I think for me, I've been very much like, 'I want this not to be an anxiety-ridden conversation' ... and so we've kind of always talked about it."
