Been doing the occasional trip with the young one since he was 6 months. he is pretty good 2500km on black stuff in two days no worries. but the third day... didn't want a bar of it. driving at night was easier for him as he loved sleeping in the car.

as he gets older i find i gotta stop every couple hours to let him run around, keeps everyone sane. yeah got a tablet for him to watch now. he also sleeps while i go through the fun tracks.

good luck with the weather
