Bedwetting in preschoolers is a common condition since most are still undergoing toilet/potty training. However, even if your child is successful in potty training in the daytime, it may still pose quite a challenge come bed-time.
Bedwetting in preschoolers is a common condition since most are still undergoing toilet/potty training. However, even if your child is successful in potty training in the daytime, it may still pose quite a challenge come bed-time.

Bedwetting, or nocturnal enuresis, is the unconscious urination during sleep. Children below 6 years old, usually preschoolers, are prone to bedwetting.
Bedwetting is normal since young children, ages 3 to 5 years old, are still adjusting to changes brought upon by potty training. Preschoolers still have a hard time waking up in the middle of the night to go pee or poop in the toilet, which results in bedwetting. Fortunately, children, ages 5 to 7 years old, are most likely to outgrow bedwetting.
Children who often bed wet feel anxious and ashamed. This is why parents must explain and let their children understand that bedwetting is a part of their growth.
Bedwetting occurs for several reasons:
Some children have an overactive bladder, which causes frequent and unintentional urination in the daytime as well as nighttime.
While your child is asleep, their kidneys may be overworking and overproducing urine, which makes the bladder full. Once the bladder is full, the brain will signal it to release the urine even though the child is still asleep.
The most common cause of bedwetting in preschoolers is deep sleep. There is a greater possibility that your child becomes a bedwetter if they are a deep sleeper. Being unable to wake up despite the urge to urinate causes bedwetting.
Built-up bowel in the rectum presses against the bladder hindering its function to hold the urine, which causes bedwetting.
A child might inherit genes from the parents that might cause bedwetting. If both the parents or a parent are bedwetters, then there is a higher chance for their offspring to inherit the trait. On the other hand, if both parents do not wet their beds, there is less to no chance that their child will become a bedwetter.
Further studies are still ongoing to prove and provide scientific evidence between the connection of genes and bedwetting.
Stress due to a change in the environment and other emotionally taxing events can cause bedwetting in preschoolers.
Vasopressin or antidiuretic hormone (ADH) is responsible for decreasing the amount of urine produced by the kidney to slowly fill the bladder. Normally, the level of ADH rises at night, which prevents the bladder from filling up quickly during sleep.
However, there are cases that the ADH does not rise at nighttime, which makes the kidneys produce the amount of urine it makes during the daytime. Bedwetting occurs when the level of ADH is low.
There are medical conditions that may cause bedwetting such as diabetes, sleep apnea, urinary tract infection (UTI), neurological problems as well as abnormalities in the kidneys or the bladder.

Here are some tips on how to manage bedwetting in preschoolers:
Bedwetting in preschoolers may be a sign of a more serious medical condition, especially if it started suddenly or returns after several months. Conditions such as urinary tract infection, diabetes, or kidney and bladder problems might be the cause of why your child bed wets.
Call your doctor if:
Always consult your doctor about treatments and medications that can help your child get through bedwetting. Communicating with your medical provider about your child’s situation will help in preventing other medical problems from developing.
Bedwetting in preschoolers can be a bit stressful for parents. However, we must understand that children are just going through another phase of their childhood.
Being more patient, caring, supportive, and loving towards children during this vulnerable phase will help them overcome bedwetting and achieve another milestone sooner.
