Night sweating

Andrea

My 1y2m old is sweating so much at night I had to change the sheets tonight. She's sweating mostly at the head. Lack of appetite and difficulty to put on weight. Other than that no other symptoms whatsoever (no fever, no coughs, no signs of pain anywhere, normal activities, drinking lots of water). Anybody got a clue as to what is it? It's so weird I'm even questioning whether I should bring her or not to her pediatrician... it started about 3 days ago
