It gets cold where I live and the bedroom might be 20 degrees celcius when the rest of the house is at 23.

The sleep sacks all have arms free which i cant help but wonder if that will be cold?

Currently I'm dressing LO in a fleece sleeper and a 1 tog sleepsack but i want to buy another 2.5 tog one and maybe do without the fleece sleeper. But I worry he will still be cold with his arms free?
