Great question, S.--- I'm sure you'll find a good balance between doing ALL the driving at night ( which means you'd be in really poor shape to let him run and wiggle during HIS up time- as you'd be ready to crash) - and making all the drive-time during time that he is usually able to run and wiggle. The greatest problem you'll have is that it is NOT natural for a child so young to be still so long- my strong recommendation is build into your plans that you will stop every 2 or 3 hours and let him play in a park, an open area - or even a McDonalds' play-place --- somewhere where he can run, and climb, and use his muscles and stretch and be a natural little boy( arent they the coolest thing ever?????????) Be sure and pack some toys that will help you to help HIM to really take advantage of his play opportunities- balls, other toys to throw and run with ---
