Thanks everyone for your feedback! For some reason I didn't get any e-mails telling me I'd got replies so didn't realise anyone had responded!
To try and answer the questions etc:
Going to Portugal for 4 nights - can't wait! First holiday since June 2008 and first holiday with DS who will be 16 months old.
Thought about buying nappies there but will need some for the car journey/flight etc and, as we're only going for 5 days, we shouldn't need more than one pack so makes sense to get them before rather than having loads left over that we'll never use.
All the feedback on here and the Natural Mamas forum has made me feel SO glad I'm using cloth - disposables all sound so unreliable and smelly! Think we're going to go for Nature Baby as DS has never had nappy rash at all and don't really want to start when we're away. He had them when he was a newborn and although they leaked sometimes they didn't affect his skin. Going to take some cloth wraps to use with them at night, so we don't get any leaks, and may use it on the flight etc - just to be sure. Didn't realise that disposables smelt.... sounds horrid!
Thanks for all your assistance -really appreciate it. Have to admit that all this disposable talk led me onto the Wee Notions site and I've just ordered 3 more cloth nappies on there.... oops!
