Baby sweating at night

Nikki

The last week when my son wakes up he’s so sweaty! At first I thought it was because I was putting him to sleep in the fleece pajamas and then his swaddle, so I switched to cotton. But he’s still sweating. He has no fever, and our house is kept at 68 degrees. He has no blankets, just the swaddle. I keep googling and it says it can be normal, anyone else’s baby sweating in their sleep?
