Nappy rash can cause lots of tears for both parents and babies, so it's important to determine the type of rash and how best to treat it.
There’s nothing cuter than the soft dimpled skin of your baby’s little bottom. But it’s very easy for this delicate skin to become chapped and irritated, leaving your little one – and you – thoroughly bummed out.
‘Your baby’s skin is 30 per cent thinner than yours, making it incredibly sensitive to anything it comes into contact with. So, combined with nappy-wearing, it’s no wonder she might get sore,’ explains dermatologist Dr Cairine Wilkinson. One solution doesn’t fix all sore bums though: with a little know-how, you can both prevent plenty of nappy-rash bouts, and sort the rest quickly.
What is nappy rash?
If your baby’s bottom is looking red and sore, there's no need to instantly think of eczema and dermatitis. It’s probably a simple nappy rash – a skin irritation that most babies will have at some point. ‘It’s likely to occur between nine and 12 months,’ says health visitor Anne White.
The three type of nappy rash:
Common-or-garden everyday nappy rash looks red, sore and appears almost shiny. Your baby won’t seem any different to her usual happy self. Change her nappy more often than normal, keep her bum clean by gently dabbing with warm water and cotton wool rather than rubbing, and let her skin dry completely before applying an emollient or antibacterial cream, and the rash should clear up in two to three days.
A stubborn nappy rash which refuses to go away with the usual treatment may be a candidal rash. Warm, wet places such as inside a nappy, provide the perfect environment for the yeast called candida to grow. A fungal rash looks similar to a normal nappy rash, but it’s bright red and scaly, as well as slightly raised. Make an appointment with your GP who may recommend an antifungal or mild corticosteroid cream.
If your little one is uncomfortable and has a rash that is weeping or has a yellow crust, she may have a bacterial nappy rash. ‘This develops when the skin has broken while your baby had a mild nappy rash, and bacteria has entered the skin, leading to an infection,’ says Cairine. Make an appointment to see your GP, pronto.
The best nappy rash creams:
Use a barrier cream as a preventative measure in your daily nappy changing routine, as long as your baby’s skin is intact. ‘It works by creating a protective, water-repellent coating over your baby’s skin, so prevents wetness from touching it,’ says Cairine. Once your tot’s bum is completely dry, apply a super-thin layer before popping on her nappy.
If the skin on your tot’s bum looks dry, itchy or scaly, then an emollient will help to get her skin back into a state where it can deal with the onslaught of all the poo and wee. They soothe, smooth and hydrate the skin, but their effects are short-lived so you’ll need to reapply frequently.
Antibacterial creams contain bacteria-killing antibiotics, so if that nappy rash is starting to look a little worse, then apply twice a day until the rash resolves. It’ll help to soothe your tot’s skin as it gets to work on that pesky bacteria, so it’ll quickly help her feel more comfortable too.
If your baby has a Candidal nappy rash, the infection will need to be treated with an anti-fungal cream like Canesten, which contains clotrimazole, an active ingredient which will relieve your baby’s symptoms while treating the infection. Get your GP's advice first, and you'll have to speak to the pharmacist before you buy it, but then apply to your baby’s bum two or three times a day, and avoid using a barrier cream until the infection has cleared.

Causes of nappy rash
In most cases, nappy rash is caused when your baby’s skin becomes irritated due to prolonged contact with faeces and urine. ‘Over time, the urea and nitrogen in his waste react together to form ammonia – creating that distinct wee smell – which then irritates his skin,’ says Dr Griffiths.
Most babies will get nappy rash at some point. If your baby has diarrhoea, this may cause nappy rash, while poos and wees after very acidic foods like fruit can also inflame skin. Sometimes the rash can be caused by a yeast called candida, which thrives in moist, warm areas like the nappy.
‘It can also be triggered by an allergy to the chemicals in disposable nappies, such as sodium polyacrylate, which is the absorbent gel, or the fabric conditioners used to wash reusable ones, so try different types and brands,’ says Anne.
