Do you have your air cond on?? just wondering as we live in one of the hottest places & Charlie was still being swaddled until about 6months & I worried about him sweating, but with a very thin wrap & the air cond on it's not a prob at all. Or perhaps you could use a fan in the room, also would just put bubs in short sleeve suit & no singlet. Some people suggest just a singlet, but I find the suits better as they don't ride up.
