I usually use reusables but went away for the weekend and DS was due a monster of a poo so I took some disposables (didn't fancy travelling down the motorway with a big bag of something nasty as a travelling companion!) I noticed that when he'd done a wee it smelled really strongly.....something I have never ever noticed with reusables. Could it be that there is something in the disposables that makes them whiffy so that you change them more frequently or am I turning into a mad conspiracy theorist!!!!:)
