Understanding TOG and choosing baby sleeping bags and cocoons?
What is the TOG of a sleeping bag?
The TOG is the thermal capacity index that allows you to choose your baby's sleeping bag according to the season. A sleeping bag can be warm or light, but above all it must be adapted to the season.
Generally between 0.5 and 4
TOG 4 is recommended in winter in a room that is difficult to heat
and the 0.5 is very light, for the very hot summer.
Baby sleeping bags are obliged to carry this TOG indication so that the parent can see the potential ‘heat’ of the sleeping bag to avoid hyperthermia.
The TOG is very important, especially for ‘complex’ sleeping bags that contain several layers of fabric, especially synthetics, which tend to overheat.
I always recommend 100% merino wool, because beyond the TOG, baby will be able to use this fibre in both summer and winter, as this wool is thermo-regulating, so you don't have to change sleeping bags between summer and winter.
So you can adapt baby's pyjamas (long sleeve + bodysuit in winter or just a bodysuit in summer), and still have a great thermo-regulating wool sleeping bag.
It replaces the sleeping bag for the first 6 months of baby's life, and lets you sleep in a reassuring cocoon made from merino wool.
It helps baby to stay together and fall back asleep between micro-awakenings, thanks to the rolled edge that gently contains baby's jolts.
Created by a paediatric physiotherapist, it is much more soothing for baby than a sleeping bag.
