With our first baby who was born in Summer, we didn't discover sleeping bags until he was a few months old and it was already winter.
This time I think we'll use a sleeping bag from newborn stage onwards, I'm due 3rd June and just wondering what tog I will need for the first 3 months. It gets very hot in our room in Summer, sometimes 25C or more. So I suppose it'll need to be the thinnest tog possible?
