Officials warn against going to Mexico because of the violence ... but dangers await even those spring breakers who stay in the U.S.

In Moms Are Talking About, we told you that the U.S. State Department and universities around the country are warning college students headed for Mexico for some spring-break partying of a surge in drug-related murder and mayhem south of the border. More than 100,000 high school- and college-age Americans travel to Mexican resort areas during spring break each year.

"We're not necessarily telling students not to go, but we're going to certainly alert them," said Tom Dougan, vice president for student affairs at the University of Rhode Island. "There have been Americans kidnapped, and if you go you need to be very aware and very alert to this fact."

As we found out in our momlogic investigation, even spring breakers who don't leave the country often face incredible dangers.

So, how can you keep your child safe? "The most important thing is to set limits," says Dr. Natterson. "If you know the situation will be wild, don't let him or her go. It is equally important to keep talking to your child. Bluntly tell him or her what worries you. Use short-term examples like: 'You won't to be able to play sports next week,' instead of talking about long-term addiction or eventual loss of brain-cells."

"While it is true that the chemistry of the teen brain, with its impulse-intensive responses, will often win out over your words of warning--your words are still valuable," says Dr. Natterson. "Every time you sit with your child and have that talk, it's another piece of hay on the haystack. Eventually the stack gets big enough that you are influencing your child's decisions."
