Your body heat is real warmth — dress your baby one layer lighter.
Carried close in a sling or carrier, your baby shares your warmth. That often means one fewer layer than a stroller would need.
Dress one layer lighter than usual Keep a hat on in cold air Cover exposed legs and feet Check the neck when you stop moving
A jacket that zips around both of you works well. Just make sure your baby's face stays clear and easy to see.
How the app counts it
In a carrier, the app counts your warmth as a few degrees on your baby's body: the sweater and the jacket are decided as if it were warmer. Legs, feet, head and hands still face the weather, so trousers, socks, the hat and mittens stay as they are.
On a dry day below 14°C (57°F), a blanket over the carrier does the jacket's job, never on top of one. A bulky jacket compresses between you and gets in the straps. In rain the jacket stays on to keep the layers dry.
What counts as a carrier
A sling, a wrap or a structured carrier, with your baby worn against your torso, chest to chest or on your back. A stroller, pram or car seat is not a carrier.
Once your baby is out of the carrier, check the neck and see if the layers still fit.
No source gives a number for this one. It is Baby Layers' own step, and the app says so.
