Feel a bit daft asking about this after the round-the-world question but we're planning on going skiing soon, won't be taking car seat (too heavy and mostly we're on public transport) and will be using friend's car which has no car seat in it when we get there. Only planning on doing short distances, 10 mins at the most, with baby (9 months by then) but am paranoid about the car seats. Would you travel about with him in your arms or insist on finding a baby seat?
