1. How long after they were day trained did you nap/nightime train?
2. What is on their bed/crib sheet/waterproof wise?
3. Did you bring them to the potty at set times during the night?

DS is in underwear all day except nap & night when he is in a pullup. He has been waking up dry from naps at least a week now and in the AM he goes a lot but must wet at least once earlier in the night.
