Baby is sweating or is it pee?

Gabriela

Some nights when I go check on my son sleeping I feel his back and diaper area. Lately I have been feeling it damp or even almost wet, but when I check with my phone light, there are no wet marks and it doesn’t smell? He doesn’t wake up from it at all and will continue to sleep right through it but I don’t know if he is sweating or peed?
