Breathing band + sleep sack
I need to purchase a new sleep sack for our son and Ive heard some things about the thickness being an issue with the breathing band. How thick is too thick for the band to read accurate breathing? I also saw that you sell a sleep sack, but do you only have a lower tog one? I’m needing a warmer one for winter and have been using a 2.5 tog. I think the one I have is probably too thick. Could you give me some advice on the thickness while using the band please?
