Ay, hadhad talaga ang hassle sa init! Better to check with your pedia muna para makita kung anong type exactly, kasi may iba't ibang remedies depending kung fungal or heat rash lang, pero in the meantime, try keeping the area dry and clean, and light, breathable clothes lang. Some moms swear by powder or anti-fungal cream from the pharmacy, pero best talaga if your doctor recommends what's safest for your baby's age at skin condition.
