So, we've always had what we know as 'the car bag' for as long as I can remember. A bag with minimal overnight supplies that stays in the car, nappies, wipes, drinks bottles, snacks, the usual. It's saved us when stuck in traffic for hours, the kids are sick when away, or we forgot to pack something. As the kids have got older needs change and I need to level up. After a disastrous Airb&b stay, we realised we could do with a few more items. Popping to the shops when away isn't always an option for us.
Does anyone do this and what items am I probably missing? We like to keep it to one rucksack.
