T., you know you children better than anyone and if you have planned this trip, you must be pretty sure the little ones can handle it. You will be stopping to feed and diaper the babies, give them hugs and kisses just as you do at home, be sure they are burped, maybe give them a little back rub, be sure everything is comfy in the car seat, and they should be fine. As for the things you may have forgotten, I doubt you will go more than 20 miles without passing a WalMart where you can pick up what you need. Right now, I hope you are getting the worry free rest you need for the day ahead of you. Our granddaughter has boy/girl twins who celebrated their first birthday last week. One thing I noticed is how much they enjoyed smiling faces talking to them. Their older sister was as good at it as their mom and dad were. If you don't already know about KMFA, 89.5 on your radio dial, you might try that for the calming effect of classical music or play your favorite CDs, or read to the four-year-old and the babies will enjoy it, too. I hope you have a calm, happy, safe trip. Oh, yes, there are always wash-a-terias if you need to run a load or two somewhere along the way. On trips for our family of five, we never took more than three days clothing for each. We camped throughout Colorado and could always find a nice place to wash and dry clothing, bedding and towels while we met other travelers and shared stories. Fun!
