My LO (5.5 months) was just sleeping. She randomly woke up because she lost her dummy and as I felt her hair it was soaking wet. It 100% was sweat and not sick/dribble as that is sticky and hardens whereas her hair just felt more wet and kind of greasy feeling (not greasy though!!) I thought I'd check her temp just incase but it came up 35 degrees which is normal for her.. When I feel her skin, even under clothes, it felt cold. She is wearing a vest, sleepsuit and a sleeping bag (1tog). Does anyone know why?
