Anybody know of (and where to get) a lightweight travel cot? I am not talking about the standard folds-up-to-a-rectangular-shape and fits in a gym bag type thing, but something that I could carry easily on public transport. (No car). Also, I saw a lightweight fold up bassinet type thing for young babies somewhere, but can't remember where. Any ideas? We are going on a 20 hr flight at Christmas with a 3 month old and don't want to rely on Am. Airlines to provide the sky cot, due to previous bad experience.
