Winter Baby Care Calculators
Free, practical 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 safe outdoor time. Informational tools, not medical advice.
Baby Layering Guide
Enter the outdoor temperature and what baby is doing to get a head-to-toe layer plan — one layer warmer than an adult, adjusted for active toddlers, with a deep-cold caution
Winter Car-Seat Safety Checker
See the hidden harness slack a bulky coat creates in a crash, get a safe / caution / unsafe verdict, and run the winter car-seat checklist for keeping baby both warm and safely buckled
Baby Room Temperature & TOG Guide
Get the safe-sleep nursery temperature range and the bedding TOG to match the season and your baby's age, with a reminder to keep young infants off loose bedding
Snowsuit Size Calculator
Find the right snowsuit or bunting size from your child's height, with age as a cross-check and a size-up recommendation when they need layering room underneath
Sleep-Sack TOG Calculator
Turn the nursery temperature into the right sleep-sack TOG and the light layers to wear underneath — from a nappy only in a hot room to a bodysuit and sleepsuit in a cool one
Baby Outdoor Time Limit Calculator
Combine temperature, wind speed, and your baby's age into a felt wind-chill temperature, a cold-risk band, and a conservative safe outdoor-time limit for infants
