From layering baby for a frosty walk and buckling them safely into a winter car seat to setting the nursery temperature, sizing a snowsuit, and knowing when the wind chill means it is time to head indoors, BabyPolar pairs free hands-on calculators with plain-English cold-weather baby-care guides and an illustrated museum. Keep your little one warm, safe, and cosy all winter.
Winter Baby Care Calculators
Free tools for keeping a baby warm and safe in the cold — cold-weather layering, winter car-seat safety, nursery temperature and TOG bedding, snowsuit sizing, sleep-sack warmth, and outdoor time in the cold.
Baby Layering Guide
Enter the outdoor temperature, what you are wearing and what baby is doing for an outdoor layer list, never more than one layer above yours (the AAP's rule of thumb)
Winter Car-Seat Safety Checker
Coats and snowsuits stay off the harness: check what goes under the straps, run the pinch test and the five-point winter checklist, in the AAP's and NHTSA's words
Baby Room Temperature & TOG Guide
Check the nursery temperature you measured against the 16-20 °C range, with the AAP's safe sleep basics
Snowsuit Size Calculator
Find the typical snowsuit or bunting size band from your child's measured height, with age as a cross-check; the brand's own chart decides
Sleep-Sack TOG Calculator
Turn the measured nursery temperature into the TOG band most sack labels give, with one light layer underneath and no figure below 16 °C
Baby Outdoor Time Limit Calculator
Combine temperature, wind and baby's age into a felt wind-chill temperature, a cold-risk band and a rule-of-thumb upper limit, with frostbite and hypothermia warning signs
Winter Baby Museum
Step into an illustrated museum of how families have kept babies warm through history — infancy and swaddling, the prams and carriers that moved little ones through the cold, the wool and winter clothing that wrapped them up, and the cradles they slept in, each in its own gallery. Get to know the long story behind the way we bundle up a baby today.
