How to Keep Your Baby Warm and Well This Winter
Winter with a baby can bring a few extra worries, especially when they are brand new. Along with keeping your little one warm and comfortable, there are the inevitable winter sniffles, coughs and bugs to navigate.
Babies have very small nasal passages, so even a little congestion can make feeding and sleeping more difficult. While it is impossible to avoid every winter cold, there are a few simple ways to help protect your babe and keep them comfortable when the sniffles arrive.
Dress your baby in warm, breathable layers
Keeping your baby warm does not prevent a cold, but it does help them stay comfortable during chilly winter days.
A helpful guide is to dress your baby in one more layer than you are wearing. Choose light, breathable layers that are easy to add or remove as the temperature changes.
Merino wool is a wonderful choice for winter baby clothing. It naturally helps regulate body temperature, keeping your baby warm while allowing excess heat and moisture to escape. Soft merino bodysuits, babygrows and sleepwear are ideal for layering without adding too much bulk.
Create a safe and cosy sleep space
For every sleep, place your baby on their back on a firm, flat mattress with their face and head uncovered. Keep pillows, toys and other loose items out of their sleep space.
During winter, it is safer to dress your baby in suitable sleepwear or a baby sleeping bag than to add heavy or loose bedding. Avoid overheating the room and adjust your baby’s clothing when needed.
Help keep winter germs away
Good everyday hygiene can help reduce the spread of coughs, colds and other winter illnesses.
Wash and dry your hands regularly, especially before feeding your baby, after changing nappies and when returning home. Encourage older siblings to wash their hands and cough or sneeze into their elbow.
It can also help to regularly clean frequently handled toys and surfaces, and avoid close contact with people who are (or have just been) unwell.
Breastmilk provides valuable nutrients and antibodies, but every family’s feeding journey is different. Whether your baby is breastfed or formula fed, continue offering their usual feeds regularly.
When your baby has a blocked nose
A blocked nose can make it harder for your baby to feed, settle and sleep comfortably.
Saline drops suitable for babies can help loosen thick mucus. You can then use a baby nasal aspirator to gently remove it, following the product instructions carefully. This can be particularly helpful before a feed or sleep.
A cool-mist humidifier may also help make a dry room feel more comfortable. Place it safely out of your baby’s reach, change the water regularly and clean it according to the manufacturer’s instructions to prevent mould or bacteria from building up.
Keep an eye on their temperature
If your baby feels unusually hot, cold or unwell, checking their temperature can help you understand how they are doing.
The Oricom Non-Contact Infrared Thermometer provides a quick reading without disturbing your little one. Always follow the user guide carefully, as forehead thermometer readings can be affected by positioning and the surrounding environment.
A fever is generally considered a temperature of 38°C or higher. If your baby is under three months old and has a fever, seek medical advice urgently.
A gentle chest rub for older babies
For babies over three months, the Nude Alchemist Chest Rub for Babies can be added to their comforting bedtime routine.
Apply it only as directed and remember that chest rubs provide comfort rather than treating or curing a cold. This particular formula is suitable from three months but there are other types of rub on the market as well. Always check age recommendations, complete a patch test and stop using the product if irritation occurs.
