Has anyone travelled with a young baby? My son will be 5 months, turning 6 months on the trip this May. We are moving from Florida to Seattle and are taking 3 weeks off work to visit with family and friends along the drive. From the day we leave home until the day we arrive it'll be a total of 3 weeks. Has anyone taken extended driving time with a young one? The actual driving itself is a little over two days and we intend to do most of the driving at night while the little one sleeps. Any other tips? We could use all the help we can get. He's been in the car from here to Georgia (8 hours) when he was a little over a month old.. But this is much further. Thanks in advance!
