What tog sleeping bag do you put your lo in if the room is 20 degrees? The gro company advises a long sleeve vest and a 2.5 tog bag for 20 or a 1 tog bag for 21. My temp is 20.6 but it feels really chilly and he's in a 1 tog. It was warmer when I came up. I find getting his temp right so hard, don't want him cold but don't want him hot!
