He has never done this previously but over the last month or so, he is literally drenched in sweat overnight - it has usually dried by the morning but he goes to bed at 8 and when I check on him at my bedtime (at 10.30ish) he is drenched and on the odd occasions he gets up in the night, he is still wet.
His PJ's and bedsheets stink by the morning and I am having to change them all the time. His hair stinks every morning...
His room is the coldest in the house - he shares with DS2 who does not sweat. He does insist on literally burying himself under the duvet which probably doesn't help but I cannot stop him doing that. Again, he has always done that so why has he started sweating so much now?
Is it hormones/age?
