DS sweats a lot - more specifically his head sweats a lot. Sure it's been warmer than usual here recently (around 30 degrees), but I've noticed it before this.
After getting him up from a sleep, there are huge, huge wet patches on his cot sheet. Originally I thought it was drool, but have since worked out it is definitely sweat. We don't overdress him and he doesn't sleep under covers - yet he still has these huge sweat patches where his head was.
Is it normal that he sweats so much? Should I be doing anything more to try and stop it?
