Mould Forming in Babies' Rooms: Understanding the Causes and Solutions

Mould Forming in Babies' Rooms: Understanding the Causes and Solutions

Creating a safe and healthy environment for babies is of utmost importance for their overall well-being. 

While we may pay great attention to factors such as cleanliness and hygiene, one often overlooked issue in babies' rooms is the formation of mould. 

In this article, we will explore the details of mould formation in babies' rooms, including poor ventilation, the use of vaporisers, furniture materials, and potential areas where mould is likely to grow.

Poor Ventilation and Maintaining Temperature

Proper ventilation is crucial in maintaining a healthy indoor environment, especially in babies' rooms. 

Insufficient air circulation can result in high humidity levels, which create an ideal breeding ground for mould. When the air is stagnant, moisture accumulates on surfaces, fostering mould growth.

To address poor ventilation, consider these tips:

Open windows regularly to allow fresh air to circulate and humidity levels to decrease. 

Utilise fans or air purifiers to enhance airflow and reduce moisture. 

Install exhaust fans in areas prone to high humidity, such as bathrooms and kitchens.

Maintaining a suitable temperature is also important. While it's essential to keep babies warm, excessively high temperatures can contribute to increased humidity. 

Finding a balance is key to preventing mould formation.

The Role of Vaporisers

Many parents use vaporisers or humidifiers in babies' rooms to combat dry air and promote a comfortable sleeping environment. 

However, it's important to understand that excessive moisture from these devices can lead to mould growth if not properly managed.

To avoid this issue:

Clean and disinfect the vaporiser regularly to prevent the accumulation of bacteria or mould.

Use distilled or demineralized water in the vaporiser to minimise mineral deposits.

Monitor the humidity level in the room with a hygrometer and keep it between 30% and 50%.

Furniture Materials and Mould Growth

Babies' rooms often feature furniture made of timber, which can be conducive to mould growth if not adequately maintained. 

Wood is an organic material that readily absorbs moisture, creating an environment where mould spores can thrive.

To prevent mould growth on furniture:

Ensure proper ventilation around the furniture to allow air circulation. 

Avoid placing furniture directly against exterior walls or in areas prone to moisture, such as near windows or doors. 

Regularly inspect and clean furniture surfaces, using mould-inhibiting cleaners if necessary.

Blinds, Curtains, and Mould Formation

Blinds and curtains provide privacy and control over natural light in babies' rooms. However, if they are consistently drawn, moisture can become trapped between the fabric and the window, leading to mould growth on the backside.

To minimise mould growth on blinds and curtains:

Keep blinds and curtains open during the day to allow air circulation.

Regularly clean blinds and curtains to remove accumulated dust, dirt, and moisture. 

Consider using moisture-resistant materials or washable curtains that can withstand regular cleaning.

Areas Prone to Mould Growth in Babies' Rooms

Knowing where to look for mould in babies' rooms is crucial for early detection and prevention. 

Here are some common areas that require careful inspection:

a. Window sills and frames: Accumulated condensation or moisture around windows can foster mould growth. 

b. Walls and corners: Poorly ventilated areas can trap moisture and become breeding grounds for mould. 

c. Carpeting and rugs: Spills, dampness, or lack of airflow underneath can lead to mould formation. 

d. Toys and stuffed animals: Moisture from drool, spills, or washing can result in mould growth if not dried thoroughly. 

e. Mattresses and bedding: Perspiration and leaks from diapers can contribute to moisture build-up and mould growth.


Maintaining a mould-free environment is crucial for the health and well-being of babies. Poor ventilation, excessive moisture from vaporisers, furniture materials, and neglected blinds or curtains can all contribute to mould formation. 

Regular inspection and preventive measures are essential to minimise the risk of mould growth in babies' rooms.
