Aww, common yan sa babies actually! A few of us moms noticed the same thing sa aming LOs, mainit ang head at palad even kung normal lang ang temp, kaya walang alalahanin usually. Basta nag-eensure ka na hindi siya overheating (check kung sobrang dami ng damit or blanket), you should be okay lang, but since it's bothering you and you want peace of mind, I'd suggest checking with your pedia just to be sure everything's fine, they can give you a proper assessment na talaga.
