Socks: Simple cotton socks help keep feet warm without restricting circulation.
Sleepsuit: A breathable cotton sleepsuit adds a warm layer while letting heat escape naturally.

Why this outfit works at 63°F
At 63°F, your baby is sleeping in a cool room that still sits within the usual recommended range for nurseries. Light cotton layers plus a 2.5 TOG sleep sack keep your baby warm enough without relying on loose blankets or hats. The sleep sack provides steady warmth, while the base layers can be adjusted if your baby tends to run hotter or cooler.
The most important factor for sleepwear is the room temperature, not the outdoor weather. A simple thermometer in the nursery can help you decide when to add or remove a layer.
