Question: 20 degrees how many blankets baby?
Answer: 16-20 - Comfortable If the temperature is 20 degrees, use either a sleeping bag with a 1 tog rating, or one blanket. If the temperature is 16 degrees, use a 2.5 tog sleeping bag, or 2 blankets. 16 will feel quite cool so put an extra blanket on over the sleeping bag or blankets.
