I have to make a long car journey with my 3.5 year old. It will take around 5-6 hours to get to our destination and I'm planning on stopping at a park half way to let her run around. She has headphones and listens to stories/music and I'm planning on taking a bag of toys for the car but we don't have a tablet or anything like that. If I'm honest I would prefer she didn't watch TV in the car. Any other suggestions to keep her occupied? Any other tips?
