These pull ups (all Huggies brands that I have tried) do not work at night time. They are fine throughout the day but every time my kids wear one to bed they soak through and wet the bed. The other brands I have tried do not have any leakage.

These have been awesome to aid with potty training. We use Pull-Ups for when we are away from home and night time. Gives good coverage for those times your little doesn't quite make it to the potty in time.
