I've had all of one weeks experience of using cloth at night. Great at first but the last 2 nights dd has wet through to the sheet. I'm using a couche wrap and bamboozles (unboostered) I am assuming it was because I need to add a booster but how can you tell if the wrap needs re-lanolising? We had a sopping wet nappy, a damp sleepsuit and a perfectly dry wrap so does that mean the wrap is ok or does it need treating because it's new?
