I am having an anxiety attack about leaving my son for a 5-day trip to Mexico. My parents will be staying with him and he is comfortable with them, but we have never left this child alone overnight, ever! I can't sleep thinking about this. I have written up a will and a letter for him "just in case" but I am plagued by indecision. I have trip insurance for this very reason - now I am having second thoughts about leaving him. Any advice from other parents out there? Maybe we can go to a family resort instead of an adults-only resort. i.e maybe Dreams instead of Secrets??
