If you’re a parent quietly changing sheets night after night, wondering why your child still wets the bed, you’re not alone. Bedwetting (also known as nocturnal enuresis) is more common than many people realise, and it can be incredibly frustrating, especially when everything else in your child’s development seems on track.
The good news? It’s not your fault, and it’s not your child’s fault either. Let’s take a closer look at what might be going on behind the scenes.
By age 5, most children have developed nighttime bladder control, but for some, it takes longer. In fact, about 1 in 5 six-year-olds still wet the bed, and even at age 10, around 1 in 20 children are affected.
Bedwetting becomes less common with age, but that doesn’t mean it's always something to “wait out.” Understanding the possible causes can help you feel more in control—and more compassionate toward your child.
A child’s bladder might not yet be big enough to hold all the urine produced overnight, or it might contract before it’s full. This can cause leakage even if the child is otherwise toilet trained during the day.
Nighttime dryness depends on the brain recognising a full bladder and responding by waking the child or reducing urine production overnight. In some kids, this communication system simply develops later.
This one surprises many parents. A full bowel can press on the bladder and reduce its capacity, triggering accidents during the night. Constipation and bedwetting often go hand in hand—and treating the bowel issue can improve bladder control.
If you or your partner wet the bed as a child, your child is more likely to experience it too. Genetics can influence when bladder control develops and how the body manages overnight urine production.
Sometimes bedwetting is caused by a medical condition, it's important to be aware that underlying health issues can play a role. Conditions such as but not limited to urinary tract infections, diabetes, constipation, and obstructive sleep apnea may contribute to bedwetting. In some children, significant emotional stressors, like moving house, a new sibling, starting school, or family changes such as separation or loss can also affect bladder control.
Although these causes are less common, identifying and addressing them early is important. That’s why it’s so important to seek medical advice, especially if bedwetting starts after a period of dry nights, is accompanied by other symptoms (like excessive thirst, pain when urinating, or snoring), or if your child seems distressed or withdrawn.
You and your child don’t have to navigate this alone. With the right information and a little support, dry nights can become the norm.
