As winter sets in across Ireland, many parents notice a familiar drop-off scene: windows propped open for fresh air, heating pipes ticking, and toddlers running around in varying combinations of fleece jumpers and short-sleeved vests. Balancing infection prevention with thermal comfort is one of the trickiest operational challenges Early Learning and Care (ELC) services face during damp, chilly Irish winters.
Quick summary
- Tusla regulations: Under the Child Care Act 1991 (Early Years Services) Regulations 2016, crèches must maintain indoor temperatures between 18°C and 21°C in play and sleep areas.
- Sleep rooms: Safe sleep guidance from the HSE and Tusla recommends keeping baby sleep rooms strictly between 16°C and 20°C (ideally 18°C) to prevent overheating, a recognised risk factor for sudden infant death.
- Ventilation requirements: Post-pandemic public health guidance and building regulations encourage cross-ventilation (trickle vents, CO2 monitors, or cracked windows) to dilute respiratory viruses like RSV and flu.
- Dressing for indoor crèche play: Layering is essential. Breathable cotton baselayers combined with a removable cardigan or lightweight sweatshirt keep children comfortable as rooms fluctuate.
- Raising queries: If you are worried your child's room is too cold or stuffy, you have a right to ask how ambient temperatures and ventilation are monitored throughout the day.
Tusla regulations on crèche heating and room temperatures
In Ireland, registered early years services are legally regulated by Tusla (the Child and Family Agency). Regulation 20 of the Child Care Act 1991 (Early Years Services) Regulations 2016 covers facilities, building premises, and environmental safety.
Under Tusla’s Quality and Regulatory Framework (QRF), crèches must adhere to clear environmental standards:
| Room Type / Area | Recommended Temperature | Regulatory & Health Purpose |
|---|---|---|
| Playrooms / Activity Rooms | 18°C to 21°C | Optimal comfort for active play, floor exploration, and table activities without causing lethargy or chills. |
| Sleep / Rest Rooms (Babies & Toddlers) | 16°C to 20°C (Ideal: 18°C) | Prevents hyperthermia (overheating), supporting safe sleep standards aligned with HSE infant sleep guidelines. |
| Nappy Changing Areas & Bathrooms | 20°C to 22°C | Slightly warmer target to protect unclothed infants from rapid heat loss during changes. |
Every crèche is required to have visible, accurate wall thermometers in each children's room. Tusla inspectors regularly inspect these logs and check whether ambient temperatures meet compliance thresholds during unannounced visits.
Winter ventilation vs. room temperature: the balancing act
Ever since public health highlighted airborne pathogen transmission, Irish crèches have placed stronger emphasis on fresh air. During the winter surge of respiratory syncytial virus (RSV), rhinovirus, and influenza, stale indoor air accelerates transmission among children sharing toys and floor space.
To manage this, many crèches follow Department of Education and HSE ventilation guidelines:
- Carbon dioxide (CO2) monitoring: Many services use continuous CO2 monitors. If CO2 levels climb above 800–1,000 ppm (parts per million), staff open high-level windows or activate mechanical ventilation to refresh room air.
- Purge ventilation: Rather than keeping windows wide open all day in freezing rain, standard practice is short "air flushes"—opening windows fully while children are outside in the garden or having lunch in another room, then closing them before re-entry.
- Trickle vents: Many purpose-built childcare facilities rely on trickle vents built into window frames or continuous heat-recovery mechanical ventilation (MVHR) systems, which bring in pre-warmed outdoor air.
If you drop your toddler off at 8:00 am and notice a window cracked open while it's 4°C outside, staff are likely refreshing overnight air. However, window openings should never create direct cold draughts over cots, sleep mats, or baby crawling mats.
Safe sleep and winter nap times
When it comes to babies and young toddlers, room temperature is a matter of safety, not just comfort. The HSE and First Light safe infant sleep guidelines clearly state that overheating poses a significant risk to infants.
Why crèche sleep rooms feel cooler
Parents walking into a crèche sleep room are often surprised that it feels distinctly cooler than the main lobby or toddler room. This is intentional. Tusla guidance expects infant sleep rooms to stay near 18°C.
Here is how crèches manage safe winter sleep:
- No loose duvets or heavy blankets: Crèches strictly adhere to HSE safe sleep guidelines. Pillows, cot bumpers, heavy padded quilts, and sheepskins are prohibited in baby cots.
- Sleep bags (gro-bags): Most Irish crèches ask parents to provide a baby sleep bag. For a room kept at 18°C–20°C, a 2.5 tog sleep bag over a regular long-sleeved cotton vest or babygrow is standard.
- Cellular blankets: If sleep bags are not used, crèches use light, breathable 100% cotton cellular blankets, firmly tucked under the mattress no higher than the baby's chest level ("feet to foot" cot positioning).
- Hats off indoors: Babies lose excess heat through their heads. Tusla regulations strictly prohibit babies sleeping with hats, bonnets, or hooded clothing indoors, regardless of external winter temperatures.
What children should wear for indoor crèche days
Because crèche rooms fluctuate between high-energy physical play and calm carpet time, dressing your child in heavy, unbreathable layers makes self-regulation difficult. Sweating during soft-play followed by sitting on a cold linoleum floor is a recipe for catching chills.
Practical winter dressing guide
- The base layer: A soft, 100% cotton vest (short or long sleeves). Cotton lets the skin breathe and absorbs moisture if your child gets hot running around.
- The middle layer: A long-sleeved cotton top or light jersey long-sleeve tee.
- The removable top layer: A zip-up cotton hoodie, cardigan, or light sweatshirt. Zips and buttons are much easier for childcare workers to pop off when indoor temperatures peak. Avoid thick, scratchy wool or heavy fleece jumpers that cannot be easily adjusted.
- Bottoms: Stretchy leggings, jersey track pants, or cotton joggers with an elastic waistband. Avoid stiff denim or lined ski-pants for indoor play, which restrict movement and cause toddlers to overheat.
- Footwear & socks: Most crèches have a no-outdoor-shoes policy in infant and toddler rooms. Send non-slip grip socks, soft leather moccasins, or flexible indoor shoes. Hard rubber soles can cause little feet to sweat excessively during active play.
Note: For advice on wet gear, puddle suits, and thermal boots for outdoor yard time, see our dedicated crèche winter gear guides.
Outdoor play: does Tusla require garden time in winter?
Yes. Tusla’s early years regulations require that children have daily access to the outdoors, weather permitting. A cold, crisp Irish winter day is not considered bad weather; in fact, fresh outdoor air helps disperse viral loads and supports physical development.
Services will usually only cancel garden time in cases of:
- Severe weather warnings (Status Orange or Red for wind, ice, or snow)
- Torrential, sustained downpours or thunder
- Unsafe outdoor surfaces (e.g., icy artificial grass or frozen decking)
Make sure you keep an all-in-one waterproof puddle suit, warm hat, and waterproof mittens in your child’s crèche cubby throughout the months from November to March.
How to raise a heating or temperature concern politely
If you collect your child and notice their hands are blue or icy cold, or conversely, if their cheeks are flushed and their neck is sweaty, it is entirely reasonable to ask about room conditions.
Here is a constructive, professional way to approach your room leader or crèche manager:
1. Observe and gather context
Check your child’s core temperature rather than their extremities. Hands and feet in babies and toddlers are frequently cooler than the rest of their body due to immature circulatory systems. The best indicator of whether a child is cold is feeling the back of their neck or their chest.
2. Speak to the room leader at collection
Avoid making an accusatory comment at a busy handover. Instead, frame your question around clothing choices and comfort:
"I noticed Conor’s back felt quite damp and warm at pickup yesterday. Are the radiators running quite warm in the toddler room in the afternoons, or should I drop him down to a short-sleeved vest under his jumper?"
Or:
"Aoife seemed quite cold when we got home today. Do you find the room gets drafty near the garden door? Would you recommend sending in a fleece-lined gilet for carpet play?"
3. Check the service's environmental policy
Registered crèches must have written policies on health and safety, safe sleep, and environmental management. You can ask:
- "Could you tell me what temperature the sleep room is usually kept at during naptime?"
- "Are window openings regulated with CO2 monitors, or scheduled around sleep times?"
If a facility has persistent heating failures during severe cold snaps (e.g., a broken central boiler leaving rooms under 15°C), the provider should notify parents. Under Tusla regulations, if a provider cannot maintain minimum required temperatures, they may need to keep children in designated warm zones or temporarily close until repairs are completed.

Frequently asked questions
What temperature should an Irish crèche room be in winter?
Tusla regulations require crèche playrooms to be kept between 18°C and 21°C. Infant sleep rooms should be between 16°C and 20°C (ideally around 18°C) in line with HSE safe sleep standards.
Why are windows open in my crèche when it is cold outside?
Crèches must balance warmth with infection control. Under public health and Tusla guidance, rooms need adequate air changes to disperse airborne viruses like RSV and flu. However, staff should use purge ventilation (airing rooms when children are outside) or trickle vents, rather than leaving rooms drafty and cold.
What should my toddler wear inside the crèche during winter?
The best approach is breathable layers: a 100% cotton vest, a long-sleeve cotton top, and a lightweight zip-up sweatshirt or cardigan that staff can take off easily if your child gets warm during active play. Avoid heavy unbreathable fleeces or stiff denim.
My baby has cold hands at crèche pickup. Does this mean the room is too cold?
Check your baby's chest or the back of their neck. If the skin feels comfortably warm and dry, their temperature is fine. Young children have developing circulatory systems, so hands and feet frequently feel cool to the touch even when their core body temperature is normal.
Do crèches still take children outside to play in cold winter weather?
Yes. Tusla early years guidelines require daily outdoor play for children's health and development, weather permitting. Unless there is extreme weather like torrential storms, ice, or high winds, crèches will take children outside, so keep waterproofs and warm accessories in their cubby.
