How to Keep a Newborn Warm in Winter Without Overheating
Winter brings a few extra challenges for new parents, especially when caring for a newborn. Newborns are more sensitive to temperature changes and need careful attention to maintain a comfortable body temperature during colder weather. However, keeping a baby warm does not mean wrapping them in multiple layers or covering them with thick blankets.
Too much clothing, heavy bedding and excessive room heating can cause overheating, which is associated with an increased risk of sudden infant death syndrome (SIDS). Keeping your baby safe and comfortable involves maintaining a suitable room temperature, dressing them appropriately, and watching for signs of overheating or feeling too cold.
For parents, understanding these simple newborn winter care practices can help you keep your newborn warm in winter in a safe and comfortable way.
1. Dress Your Newborn in Light, Comfortable Layers
A useful general guideline is to dress your baby in one more layer than an adult would comfortably wear in the same environment. For example, a soft cotton vest, a full-sleeved sleepsuit and an additional light layer may be suitable in a cool room.
Opt for breathable fabrics and comfortable clothing that keeps your baby warm without restricting movement.
Remember that every baby and environment is different. Premature babies and babies with low birth weight may need additional temperature support under medical guidance.
2. Check Your Baby’s Temperature the Right Way
A newborn’s hands and feet may feel cool even when the rest of their body is comfortably warm. Therefore, these areas alone may not accurately indicate whether your baby needs an extra layer of clothing.
Instead, gently feel your baby’s chest, tummy, or the back of their neck. These areas can help you assess whether your baby feels comfortably warm.
Signs that your baby may be overheating include:
- Sweating or damp skin
- A chest or back that feels unusually hot
- Flushed or reddened skin
- Unusual discomfort or restlessness
If your baby feels too hot, remove an extra layer and reassess their comfort. If you suspect a fever, use a digital thermometer rather than relying only on touch.
For a newborn younger than three months, a temperature of 38°C (100.4°F) or higher requires urgent medical assessment.

3. Follow Safe Sleeping Practices During Winter
Keeping your newborn comfortably warm at night is essential, but always prioritise safe sleeping practices.
Place your baby on their back on a firm, flat mattress in a separate cot or bassinet in your room. Keep the sleep area free from pillows, quilts, loose blankets, soft toys and other objects that could cover your baby’s face or obstruct breathing.
A properly fitted, non-weighted baby sleeping bag may be a suitable alternative to loose bedding. Choose one appropriate for the room temperature and follow the manufacturer’s clothing and tog guidance. If a blanket is used, choose a lightweight one, tuck it in securely, and keep it below your baby’s shoulders to support safer sleep.
Avoid covering your baby’s head while sleeping, and remove indoor hats once you are home from the hospital. Do not use hot-water bottles, electric blankets or direct heaters to warm the baby.
Overheating is a recognised risk factor for SIDS, so a comfortable sleeping environment is safer than excessive bundling.
4. Maintain a Comfortable Room Temperature
A newborn does not need an excessively warm room to sleep comfortably during winter. NHS safer-sleep guidance recommends keeping the room at around 16–20°C, though premature or medically vulnerable babies may need additional temperature support based on medical advice.
Keep the room comfortable and avoid placing your baby directly beside a heater, fireplace or other heat source. If you use a room heater, follow its safety instructions and ensure that it cannot burn the baby or create a fire hazard.
Avoid directing hot air straight at the cot. Instead, focus on maintaining a stable, comfortable environment and adjusting your baby’s clothing as needed.
If your baby was born prematurely, has a low birth weight or has difficulty maintaining body temperature, ask your paediatrician for individualised advice.
5. Use Skin-to-Skin Contact to Support Warmth
Skin-to-skin contact can help newborns maintain body temperature and support bonding and breastfeeding.
When you and your baby are awake, place the baby against your bare chest, with their head turned to one side, their nose and mouth visible, and their neck in a position that allows easy breathing. Cover the baby’s back with a light blanket if needed.
A parent should remain awake and attentive throughout skin-to-skin contact. If you feel sleepy, place your baby on their back in their own safe sleep space.
Skin-to-skin care is particularly important for babies who need additional temperature support. If your newborn continues to feel unusually cold or struggles to stay warm, consult a healthcare professional promptly instead of relying solely on extra layers of clothing.
6. Take Extra Care When Bathing or Going Outdoors
Bathing and moving between indoor and outdoor environments can cause newborns to lose heat quickly.
When bathing your baby, keep the room comfortably warm, prepare everything in advance, and use comfortably warm water. After bathing, dry them promptly, including skin folds, and dress them in clean, comfortable clothing.
When taking your baby outdoors in cold weather, dress them in comfortable layers and use a hat to help keep them warm when needed. Remove the hat and bulky outer clothing when you enter a warm indoor space or vehicle.
Never cover a pram or stroller with a thick blanket that restricts airflow, and keep your baby’s face visible. Avoid exposing newborns to extreme cold or strong winds for prolonged periods.
7. Know When Your Newborn Needs Medical Attention
Since newborns are more sensitive to temperature changes, parents should watch for warning signs and seek prompt medical advice if anything seems unusual.
Seek urgent medical assessment if your baby:
- Has a temperature of 38°C or higher
- Feels unusually cold and remains cold after appropriate warming
- Is difficult to wake
- Feeds poorly
- Breathes abnormally
- Appears unusually weak
Seek emergency medical help immediately if your baby is unresponsive, has severe breathing difficulty or develops blue or grey colouring around the lips or skin.
Do not try to treat suspected hypothermia or fever in a newborn by using hot-water bottles, direct heat or excessive layers. Medical assessment is important because temperature changes can sometimes indicate an underlying illness.
Final Takeaway
Keeping your newborn warm during winter requires a careful balance of comfort and safety. Dressing them in lightweight layers, monitoring their temperature, maintaining a comfortable room environment, practising skin-to-skin contact while awake, and following safe sleep guidelines can help protect them from both the cold and overheating.
Every newborn has individual needs, especially babies born prematurely or with low birth weight. If you are unsure about your baby’s temperature, feeding, or general well-being, seeking advice from a qualified paediatrician is always the safest choice.
