We are making the 300 mile trip to introduce our 16 week old dd to DHs grandparents in a couple of weeks as unfortunately they are too ill to travel. We are breaking the journey up on the way there with a overnight stay roughly half way but on the way home we’ll be doing the trip all in one go! We will be making regular stops to give dd a break from the car seat but I just wondered if anyone has any other tips so make it slightly less painful! I’m beginning to worry about it a bit!!
