They need changing so often even overnight, and you will find it is actually often a helpful part of your feeding routine , so we never used one either.
I think the first time we used a nappy with the hope of it going all night was around 4-5 month? And it was a double boosted BumG. Worked perfectly here until she was over 1. I bought a dedicated night nappy at around 9 months, but still only has 3 by the time she was 14 months, so double boosted BumGs were the go most nights here - and they dry quicker! lol
