Ay, hindi ako nakaencounter ng ganitong condition sa baby ko, pero alam ko na may mga moms sa group namin na nag-alala about skin reactions sa lamig! Honestly, if you're noticing hives or rashes sa baby every time may malamig na panahon or exposure, worth it talaga mag-check with your pedia kasi marami-maming possibilities at kailangan ma-rule out ng doctor properly. Have you noticed if it happens consistently or certain times lang? Mahirap mag-self-diagnose sa babies dahil sensitive ang skin nila, pero ang good thing is pedia usually can identify it right away, bring photos if you can. Hope baby feels better soon!
