Nothing here too. Both girls were quite late with TTing, and after a few days of not having accidents during the day they each said they wanted knickers over night. Touch wood, DD1 has never wet the bed to this day. DD2 never wet the bed until a month or two before DD3 was due and she started having a few accidents, which thankfully have stopped now. The brolly sheets wouldn't have worked for us, but that's because of the way she sleeps - twisted and wrapped in her top sheet and doona. The times she has wet the bed have resulted in EVERYTHING needing to be washed.
