My 6 week old has become a right wriggler so I'm looking at getting him a sleeping bag however our room during summer sits right on the cusp for guidelines about which tog to get (22 degrees but drops slightly on a warm night, ect). I'd be more inclined to get a 2.5 as this is more versatile but there is times the room might be above 21 degrees. I'm already going to have to get 2 of whichever one I get because he's such a sicky baby so I really don't want to buy 2 2.5 tog ones and 2 1.5 tog ones.
What would everyone suggest?
