Nappy rash
Nappy rash is very common. The best way to treat ordinary nappy rash is by changing the nappy regularly and also allowing the baby's bottom to get some fresh air.
Why do babies get nappy rash?
Nappy rash is very common - most babies will get it at some point. It is not usually a 'disease', but just an irritation of the skin.
A wet or dirty nappy that has been left touching the skin for too long is the most common cause of nappy rash. This is especially true of children with diarrhoea. Human waste products can turn into ammonia if the nappy isn't changed for a long time. Waste products eat into the baby's skin, which can then start to sting.
A fungal infection due to dampness under the nappy also causes nappy rash. Everybody has fungi on their skin, but it only grows when conditions are right. This has nothing to do with bad hygiene. It is caused by dampness or changes in the skin conditions. A fungal infection can be quite unpleasant for the baby because it can sting the skin - especially when the baby wets or dirties its nappy.
The baby can also get a bacterial infection in the area where the nappy is. This can happen if there has been a small scratch on your baby's skin or if their skin has been weakened by a sustained rash, allowing bacteria to grow easily. The baby's skin will then be red, warm and swollen, and the baby may also get a fever. If your baby has these symptoms, you need to contact your doctor.
Other skin conditions, such as infantile eczema, will exacerbate your child's nappy rash. Untreated, the baby's skin falls off in big flakes, and pus-filled blisters may develop; the nappy dermatitis is also likely to spread beyond the nappy region.
What can you do about a nappy rash?
Some babies only experience it once in a while, whereas others experience it time and again. No one knows the reason for these differences in the skin, but some babies just seem more sensitive than others.
The best way to treat an ordinary nappy rash, or nappy rash caused by a fungal infection, is to let it get some air. It is a good idea to leave the baby's nappy off for about an hour a few times a day.
It also helps to change the baby's nappy often. When the rash is at its worst, it may be necessary to change the nappy up to 12 times a day. Dry the baby's bottom carefully after each change.
It is important to wash the baby's bottom every time you change the nappy. If your baby has only wet their nappy, use warm water. If the baby has dirtied their nappy, use a little soap, but remember to always rinse in warm water to make sure there is no soap left on the baby's skin.
Fixed faeces can be removed by using ordinary cooking oil on a wad of cotton wool. Do not use baby wipes, as they can sting and dry the skin out and the chemicals in them can make the rash worse.
If your baby has nappy rash or very sensitive skin it is a good idea to protect it with a thick barrier cream after every wash. To protect the red skin, you can use a zinc paste or barrier cream, which is available at the chemist: zinc forms a protective surface over the skin. Weak hydrocortisone creams can be used for severe cases, but these should not be used without consulting your doctor first.
If using cloth nappies, try changing to disposable nappies as they absorb more fluid from the baby's skin.
Try dressing the baby in woollen underwear on top of the nappy instead of plastic pants.
If using disposable nappies, try switching to cloth nappies. Sometimes changing to another type of nappy will help.
What if the nappy rash just gets worse?
How to tell the differences between nappy rashes
If the nappy rash does not get better in a few days, or gets worse, talk to your doctor or health visitor. If the baby's skin turns even more red, warm and swollen, and the baby gets a temperature, you should also contact a doctor immediately as the nappy rash may be caused by a bacterial infection that requires medical treatment.
A fungal infection is bright red. Check if the baby is red in the folds of the skin as well. The fungus can grow there too. Your baby will get very upset and cry when you change their nappy. The ordinary advice such as airing the bottom and frequent nappy changes is often not enough to improve the condition. If zinc paste for children does not help, contact a doctor.
A bright red, very warm and swollen nappy rash may be caused by a bacterial infection. The baby may be in a bad mood and have a fever. If so, contact a doctor.
