When weeing, the muscles of the bladder wall squeeze the urine out of the bladder and at the same time, the muscles in the sphincter relax to let the urine flow down the urethra. The valves between the ureters and bladder prevent urine flowing backwards up to the kidneys.

Keeping your child’s bladder healthy

There are many ways you can encourage your child to have a healthy bladder – here are some suggestions:

Using the toilet

During the school day, your child could make sure they visit the toilet at the start and end of the school day and at every break or playtime. Children may rush going to the toilet if they are worried they will miss exciting playtime so encourage them to spend as long as needed. If your child seems reluctant to use the toilets at school, try to find out why and then talk to their teacher.

The nurses may advise you to encourage your child to go to the toilet at set times – every three to four hours – during the day even if they do not need to pee. Some children find a watch with an alarm a useful reminder to go to the toilet.

Getting in the right position on the toilet is important too – sitting on the toilet seat with legs wide apart resting both feet flat on the floor if they can reach. If your child cannot reach the floor, you can buy a plastic step from most chemists or childcare shops. Boys who stand up to wee should stand with their legs apart in a comfortable natural position.

We may suggest that you encourage your child to use ‘double voiding’. When your child has finished weeing, ask them to stay on the toilet and relax for 20 seconds or so before trying to wee again.

Drinking plenty of fluids

Fluids are vitally important in keeping healthy so encourage your child to drink plenty of liquid throughout the day – more if the weather is hot. It is better to drink small amounts of fluid frequently throughout the day rather than lots in one go when thirsty. Guidance from the National Institute for Health and Care Excellence (NICE) suggest the following amounts for children and young people.

• seven to 12 months – 600ml
• one to three years – 900ml
• four to eight years – 1200ml
• boys aged nine to 13 years – 1800ml
• girls aged nine to 13 years – 1600ml
• boys aged 14 to 18 years – 2600ml
• girls aged 14 to 18 years – 1800ml

Some drinks are better for the bladder than others – drinks containing caffeine or artificial sweeteners or fizzy drinks can irritate the bladder. Fruit squashes are a good alternative to water but only if they are diluted well, but darker coloured squashes such as blackcurrant are best avoided.

If you are not sure which drinks are irritating your child’s bladder, you could try limiting them to milk and water for a couple of weeks before introducing other drinks one at a time.

Avoiding constipation

The same muscles control pooing as well as weeing so constipation can affect how your child wees. Eating a healthy diet with a wide range of fruit and vegetables is usually enough to keep your child’s bowels working properly. Drinking plenty of fluid is important as well. Some families find introducing probiotic yoghurts or drinks, helps avoid constipation. They also change the bacteria in poo reducing the risk of urinary tract infection.

When your child has had a poo, teach them to wipe from front to back as this reduces the risk of germs in poo being transferred to the urethra and then into the urinary system. This is particularly important for girls as there is a shorter distance between the anus and urethra.

Straining to have a poo can weaken the muscles supporting the bladder (pelvic floor muscles). Encourage your child to eat a balanced diet and drink plenty of fluids to prevent constipation. If you are concerned about your child’s constipation, talk to your family doctor (GP) or local community pharmacist (chemist).

Health supplemental

Health supplements such as probiotics e.g. Yakult, Actimel, Cranberry, Blueberry juices, and D-mannose can reduce the risk of developing an infection. Talk to your child’s urology CNS for further details.

Good hygiene

Our skin is our best barrier against infection and the skin around the genitals is no different. Your child should wash every day, paying particular attention to this area. Water and a gentle pH balanced soap is best for keeping clean, but try to avoid using highly perfumed soaps or shower gels as these can be irritating.

Every member of the family should have their own flannel and towel to avoid germs being passed from one person to another. These should be washed frequently on a 60° wash cycle with no biological soap powder or liquid. Towels and flannels do not need fabric softener as this reduces their absorbency.
