Anyone used an ergo cocoon?

Bought one for 6wk old ds to try as his windmill arms are causing havoc whacking himself in the face and cot bars. Have got the right size for his age, it's stretchy cotton but it seems tiny! Is that right? What did your doc wear under it & what bedding over it? Room is 18 deg give or take, I'm thinking vest & sleep suit under & cellular over? It's 0.2 tog so very thin material.

Hi cake I have just got one for DS 17 weeks- notnused it yet- I have 3-12 month size - it is snug looking but I presume that is to create the Swaddle effect.
Mine came with a tag containing a room thermometer and guidelines for other layers. That would help if you had one?

Hi live mine came boxed but no extras! I used it last night, ds went an hour longer between feeds maybe he's a bit more settled in it? It's a snug fit the only thing is the neck is a bit more snug than I would like so I didn't do it up right to the top, maybe it'll loosen with use.
