Thrush in your baby or toddler often looks more alarming than it is, but it immediately raises questions. Can your child still go to daycare? Is it contagious for the other children? And how long does that white coating in the mouth actually last? As a working parent, you mainly want to know where you stand. This article gives you clear answers about oral thrush, nappy rash caused by thrush, RIVM guidelines, and how to discuss this with your childcare provider.
What exactly is thrush and how do you recognise it?
Thrush is a fungal infection caused by the yeast Candida albicans. This yeast occurs naturally in the mouth and on the skin of almost everyone, but in babies and young children it can sometimes grow into a noticeable infection. This happens more often when the immune system is still developing, after a course of antibiotics, or with prolonged moist skin in the nappy area.
You recognise oral thrush by white, cottage cheese-like spots on the tongue, gums, or inside of the cheeks. These spots cannot simply be wiped away, and underneath the white layer is red skin that often bleeds slightly. Your baby may have difficulty drinking or eating because of this and is sometimes more fussy than usual.
Nappy rash caused by thrush looks different: bright red, shiny skin with small satellite spots around it. This rash is often found in the folds of the groin and can be painful during nappy changes. Sometimes children have both forms at the same time.
Is thrush contagious for other children at childcare?
There is an important difference between the two forms. Oral thrush is hardly contagious in practice. The Candida yeast already lives in most people without making them ill. In babies with a still-developing immune system, the yeast can grow into thrush, but this is not a classic infection from one child to another.
Thrush in the nappy area is also not contagious in the usual way. The yeast is already on the skin and only grows out under certain conditions, such as heat, moisture, and a disrupted skin microbiome. Direct contact with another baby does not automatically lead to them getting thrush.
Nevertheless, many childcare locations have their own policy. Just as with chickenpox at childcare, childcare workers look not only at what the RIVM says, but also at how your child is feeling. Does your baby have a lot of pain when drinking, is there a fever, or does your child need extra one-on-one attention that is difficult to provide in a group? Then the childcare provider may ask you to stay home, even though there is no legal exclusion requirement.
What does the RIVM say about returning to childcare?
The RIVM guidelines for childcare distinguish between childhood illnesses that carry an exclusion requirement and conditions where this is not the case. Thrush falls into the second category. There is no legal obligation to keep a child with thrush at home from the daycare center (kinderdagverblijf/KDV) or after-school care (BSO).
This means that your child may theoretically go to childcare, as long as he or she otherwise feels well and can eat and drink normally. In practice, many locations work with their own illness policy. Some daycare centers ask parents to report oral thrush so they can be extra alert about hygiene around dummies, bottles, and cuddly toys. With severe nappy rash, you may be asked to stay home until the treatment takes effect and your child is in less pain.
Important to know: the RIVM does advise being extra careful with children who have a severely weakened immune system. This does not apply to the average healthy baby or toddler.
How do you treat thrush in your child?
Treatment for thrush is usually simple and effective. For oral thrush, your baby or toddler gets an antimycotic in drop form, usually miconazole or nystatin. You drop the medicine into the mouth after feeding, on the spots with the white coating. It is important to do this consistently, even if the symptoms already seem to be disappearing, otherwise the infection will come back.
For nappy rash caused by thrush, there is often an antifungal cream that you apply thinly to the affected skin. It also helps to keep the skin as dry and fresh as possible: regular nappy changes, letting your baby lie without a nappy for a while, and using a protective cream with every nappy change.
Are you breastfeeding? Then it is wise to also have your own nipples checked. Thrush can be passed back and forth between mother and child, causing the infection to keep returning. Treatment of both at the same time is then necessary.
When do you contact the GP?
Thrush usually clears up within one to two weeks with the right treatment. However, there are times when you should call the GP:
- Your baby refuses feeds or drinks significantly less
- There is a fever above 38.5 degrees
- The symptoms get worse despite treatment
- The nappy rash bleeds or blisters with pus develop
- Your child has thrush more than three times a year
With recurring thrush, the GP can investigate whether there is an underlying cause, such as reduced immunity or undetected diabetes in older toddlers.
How do you communicate about this with childcare?
Open communication works best. Report via the intake or parent app that your child has thrush, which form, and whether treatment has already started. Ask about the specific policy of the location. Some daycare centers record this in the child tracking system so that all staff are informed.
Also ask how they handle hygiene around bottle feeding, dummies, and cuddly toys. With oral thrush, it is sensible to clean these items extra thoroughly and not share them with other children. The childcare provider usually already knows how to arrange this, but it helps if you also do this consistently at home.
Just as with hand, foot, and mouth disease at childcare, thrush is mainly a matter of common sense: look at your child, follow the treatment, and coordinate with the childcare workers. Want to know how your childcare provider deals with childhood illnesses and hygiene? On Kiddie.nl you can find locations with extensive information about their illness policy and Municipal Health Service (GGD) reports.
Can thrush come back and how do you prevent it?
Yes, unfortunately thrush can recur, especially in babies who frequently use antibiotics or who are prone to skin irritations. Some practical tips to prevent recurrence:
- Clean dummies, bottle parts, and teething rings regularly by boiling or sterilising them
- Replace toothbrushes in older toddlers after recovery
- Keep the nappy area dry and airy
- Avoid using the same nappy brand for too long if your child reacts to it
- When breastfeeding, also pay attention to your own nipple hygiene
Thrush is annoying, but rarely serious. With the right treatment and good coordination with your childcare provider, it is manageable. Compare different childcare locations on Kiddie.nl for their approach to health and hygiene, so you know in advance where you stand when your child is not quite feeling well.
