Or am I being stupid? He's 7 months old, and doesn't usually sleep well. Last night he slept through, which is unheard of, he woke up for an hour, and has now been asleep since 9:30. Under his head is a huge patch of sweat, about 3x the size of his head. He's super clammy but no temperature. Yesterday he got really worked up in the evening and ended up with a heat rash all over his chest. It disappeared after an hour and I didn't think anything else of it.
I phoned 101 and they said a doctor will ring me back at some point before 2 (hopefully). I'm guessing not many people about on a bank holiday weekend.
Am I worrying over nothing?
For context, my son was admitted to hospital a while back because he went blue and stopped breathing. This was completely benign and nothing to worry about but it's left me terrified.
