I feel like Sofia hasn't been feeling well for the last couple of hours. She hasn't been sleeping for more than 15 minutes or so and she's been more fussy. Plus her nose has been stuffy. She felt feverish to me but when I took her temp, it was normal. Anyway, she just fell asleep on me and now she feels cold but is sweating. So I googled cold sweats and the first few things that came up talked about sids and of course now I'm freaking out. Should I be worried about the cold sweats? Or is it normal based on how she's been feeling??
