Set the temperature and see what your baby should wear, outside, at home or for sleep, with the TOG. The same rules as the Baby Layers app, with sources.
Pick where your baby is, set the temperature and see the layers the Baby Layers app would suggest, piece by piece.
The tool runs the same rules as the Baby Layers app, ported line for line. Each piece comes on at its own temperature, so a degree up or down changes one piece at a time.
Newborns are dressed as if it were a little colder, easing off by six months. Toddlers are dressed a touch lighter. Wind and rain make it feel colder, sun warmer.
For sleep, the sack follows the room at every age, and nothing makes it warmer than the makers' TOG chart. A baby is safer slightly cool than too warm.
How do I know if my baby is dressed right?
Check the chest or the back of the neck, not the hands. Warm but not sweaty is just right. Hands and feet often feel cool even when a baby is comfortable. A sweaty neck, flushed cheeks or a hot tummy usually mean one layer too many.
Should my baby wear one more layer than me?
In the cold, yes. The NHS and the American Academy of Pediatrics both suggest one more layer than an adult would wear. In hot weather the NHS suggests a single lightweight cotton layer.
What should my baby wear to sleep?
A bodysuit and a sleep sack with the TOG matched to the room, and nothing on the head. No loose blankets, and never a hat for sleep. The TOG chart on this site shows the whole table, room by room.
Is the tool the same as the app?
It runs the same dressing rules and gives the same layers and TOG for the same temperature, place, age and setting. The app adds a birth date that moves the answer month by month, your own clothes, and a Why this? sheet for every answer.
