We're going en famille to Amsterdam at the weekend to stay with friends who live there. We're flying there and our friends are picking us up at the airport. They've tried to borrow a carseat but haven't been able to so we went out and bought a very light booster seat recommended for 3 year olds, minimum weight 32lbs. Dd is 2 and a half, tall and heavy for her age - about 29lbs. Once we get there we won't be travelling by car much at all (although, yes, I know it only takes one journey to have an accident). Honestly, would you think it'll be ok or would you not risk it? The alternative is to take the train and tram to the city centre (avec pushchair and bags).
