We're looking at going away (and possibly eloping!) in the summer when our daughter will be turning 1. It will be for 1 or 2 weeks depending on how much time off my fiancé can get. We live in Buckinghamshire and we'd love to go to Devon/ Cornwall so we're looking at a 4/5 hour drive. That's a long time for baby to be in the car seat so we're thinking of stopping at a service station halfway for an hour or so. I'd also sit in the back with her to keep her entertained.
Is there anything else we need to think about or take with us for a long journey and holiday?
