"We won't offer her tastes because we're trying to show her that drinking wine is a responsibility," said the northern Virginia mom. "You have a responsibility when you start drinking anything, wine or whatever it is, and you need to be able to make good decisions and until you're 18, 21, your brain isn't fully formed."

Melissa Moog, a mom of three and founder of Itsabelly Baby Planners, a new parent and baby safety consulting service, also won't be letting her kids enjoy sips of wine and beer.

"I think a legal drinking age was established for a very good reason," said Moog of Portland, Oregon. "If I allowed my daughter at 16 to try a sip, I would be nervous that she'd think subconsciously that I was OK with her drinking before the legal age limit because I let her take a sip of my drink."

While I admit I am still as confused as ever about what I will do when my girls get older, there are a few things I am pretty certain of that are backed by strong evidence.

I won't ever get drunk in front of my kids, with studies showing that children who see their parents drunk are more likely to get drunk themselves.

And I will talk to my girls about alcohol as they get older. That's the focus of the #TalkEarly online campaign by the Foundation for Advancing Alcohol Responsibility, encouraging parents to have conversations early so as children get older, the topic of drinking is not taboo.

A big focus is also encouraging parents to watch what they say and do in social media, including making jokes about needing a glass of wine.

"Avoid transmitting the 'I need a drink' message after a long day or stressful situation, and talking about what it feels like to get drunk," said Micky Morrison, a mom of two and founder of BabyWeight TV.

Michelle Staruiala, a mom of three in Saskatchewan, who said her kids rarely see her have a drink, is proof good communication can lead to positive results.

She has always talked with her kids about everything, she said, and recently asked her 16-year-old son why he sometimes doesn't go out with his friends.

"He's like 'Mom, some of them are drinking ... I don't feel comfortable being around those situations.' "

"He's really, really listened to our talks and he, to this day, never has had a drink in his life. So being 16, nowadays that's kind of a rare thing," she added with a laugh.
