Baby sweating

Abi • 22- Mommy to baby Hugo 06.03.19👶🏻💙

Is this sweating normal? I just changed his nappy on his changing mat and the back of his head is soaking wet when I picked him up, this has happened a few times now.

Temperature is normal and he doesn’t feel hot?

Just wondering if anyone has experienced the same?

He is 16 weeks tomorrow btw🥰
