Regarding “pay” that comes in several forms. You’ve made the list, checked it thrice and still missed something along the way. A sip cup, a Binky, or a lost shoe while your son’s snoozing in the stroller. No worries. Extras will happen and that’s where budgeting extra money—and time, remember?---come into play. Maybe you’ve packed one less pack of diapers and while on the gondola, your infant son goes through the last of the last. To the nearest store Daddy goes to get the right sized pack of diapers.

Another plan for essentials: when the kids get the “gimmes!” and the “I wannas!” while on your holiday. “Daddy, gimme this!” “Mommy, I wanna have that!” Okay. No worries, this is budgeted, right? You planned for this, right? So, they get their “gimme” and their “wanna” essential. Other essentials: whatever they can get from Europe they can’t get back home. This could be a CD, an MP3 case, a cell phone cover, a poster, a tee shirt, a perfume or a pair of sneakers.

Here’s a thought: What if they ask for something totally out of your budget, like a food item they know they can’t get back home? Hmmm. You could share the entrée or dessert—or simply say “No.” Now, if they’re older and saved their own money for the trip, sure, they’re free to purchase whichever they wish. But, if they’re younger and have a fit of the “I wannas,” it might be time to veto that request in a firm and loving manner.
