Winter can be a challenging season for parents, especially when it comes to keeping their babies warm and comfortable at night. Balancing warmth and safety is crucial, as babies can be more sensitive to temperature changes than adults. For parents seeking tips on how to dress infant in winter, Snuggle Cubs provides a complete guide to help ensure your little one sleeps soundly through cold nights
Why Winter Sleepwear Matters for Infants?
Babies have a limited ability to regulate their body temperature, making them more susceptible to both overheating and getting too cold. Proper winter kids pyjamas helps maintain a comfortable body temperature, reducing the risk of wake-ups due to discomfort and promoting longer, more restful sleep. Additionally, safe winter sleepwear follows guidelines designed to prevent sudden infant death syndrome (SIDS) by keeping the baby’s sleep environment free from hazards like loose blankets and excessive clothing.
The Ideal Room Temperature For A Baby
A good rule of thumb for newborn winter dresses is to maintain the room temperature between 16–20°C (61–68°F), which promotes safe, comfortable sleep.
Use a reliable room thermometer to check the nursery temperature throughout the night. Some baby monitors have built-in thermometers, or you can opt for a separate digital thermometer for accuracy. If you find the room too cold, consider adding a heater (always at a safe distance from the crib) or using draft stoppers to reduce chilly air from windows or doors.

How To Dress Infant In Winter?
+ Daytime
As a general rule, your child should wear one more layer of clothing than you. For example, if you're wearing a t-shirt and a sweater, dress your child in a vest, pajamas and a cardigan or sweater. If you shiver, your child may be cold too.
Remove hats and extra clothing as soon as you're in the house or getting into a warm car, bus or train, even if it means waking your baby.
+ At night
It can be very tempting to wrap a baby to keep them warm. However, we know that overheating a baby increases the risk of AIDS (also known as sudden infant death syndrome). Research shows that it is better for babies to be less warm than too warm.
It is sufficient to use disposable clothing and a sleeping bag (check the manufacturer's recommendations for the thickness of the winter layer) or a sheet and/or blanket.
If you use a sleeping bag and your child is cold, put another layer of clothing on top, but not a blanket. If you use sheets and/or blankets, use lightweight mesh blankets. Avoid thick, fluffy or soft blankets.

Essential Layers for Dressing Newborns in Winter
How to dress infant in winter? Dressing a baby for winter sleep usually involves three main layers: a base layer, a middle layer, and an outer layer. Each layer serves a purpose in keeping your baby warm and cozy.
Base Layer for Warmth and Breathability
The base layer is closest to your baby’s skin, so it should be soft, breathable, and moisture-wicking to help regulate body temperature.
Recommended Base Layers:
Organic merino bodysuits: Gentle and breathable, organic cotton is ideal for sensitive skin and comfortable in various temperatures.
Merino wool onesies: Merino wool provides warmth and wicks away moisture, making it a great base layer for particularly cold nights.
Middle Layer for Added Warmth
The middle layer acts as insulation, adding extra warmth without being too bulky. Footed pajamas or sleepers work well here, offering full coverage for warmth without restricting movement.
Recommended Middle Layers:
Organic wool pajamas: Choose lightweight options for flexibility and easy movement.
Long-sleeved sleepers: Soft, breathable sleepers are ideal as a middle layer for keeping babies warm.
Outer Layer for Safety and Warmth
The outer layer should be TOG-rated, which is Newborn & Baby Essentials for winter sleepwear. A sleep sack or wearable blanket serves as the outermost layer, providing warmth and safety without the need for loose blankets.
Recommended Outer Layers:
2.5 or 3.5 TOG sleep sacks: Based on room temperature, select a TOG rating that offers the right level of warmth.
Swaddles (for younger infants): If your baby is still swaddling, opt for a TOG-rated swaddle that can replace loose blankets.

Newborn Clothes Size Guide
Size 000 is for babies from 0 to 3 months and size 00 for babies from 3 to 6 months. Some larger newborns can go straight to size 00. You may have to roll up the sleeves, but this won't last long.
Sizes vary according to garment type and manufacturer. So it's worth comparing garments with others you already own, and not relying solely on the size indicated on the label.
Children grow very quickly, so it's best to buy a minimum number of garments in each size.
