TOG (Thermal Overall Grade) — a measure of how warm a baby sleeping bag is
The number on the label of a baby sleeping bag: the higher it is, the warmer the bag. According to manufacturers' charts, 0.5 TOG is for a room above 24°C, 1 TOG for 20–24°C and 2.5 TOG for 16–20°C. Portuguese flats are often chilly in winter, so 2.5 TOG is the usual recommendation for that time of year.
Where you come across it. Parents' conversations about how to dress a baby for the night in winter.
Choose by the temperature in the bedroom, not by the month: in a warm flat a 2.5 TOG bag will feel "like a down jacket". Check how warm the baby is by feeling the back of their neck and their back.
