I wear ABU Kiddo Diapers mostly during the day but I do sometimes wear them during the night and I've trained myself to wet the bed again and I'm a really heavy wetter.
ABU Kiddo Diapers do hold up well overnight to my heavy nighttime wetting.
If you're looking for a fun and cute but very absorbent nighttime diaper for bed wetting then ABU Kiddo Diapers will work great.
ABU Kiddo Diapers also work well for the daytime as well and I've worn an ABU Kiddo Diaper all day before when out and about and was unable to change and it held up very nicely to my wetting.
