If your preschooler is working on staying dry during the day but seems to have frequent accidents, sleep might be part of the puzzle. Research suggests that children sleeping less than recommended amounts are more likely to have daytime wetting issues at school age. Kids who consistently get over 8½ hours of sleep nightly tend to have fewer accidents. Sleep problems themselves—like frequent night waking or breathing issues during sleep—are also linked to ongoing accidents. The connection likely works both ways: good sleep supports your child's physical development and their ability to recognize bodily signals. So if potty training feels stuck, it's worth looking at your child's sleep first. Are they waking frequently? Do they seem rested? If sleep seems off, talking with your pediatrician about both sleep and toileting together often helps clarify the bigger picture.
