Ay, ang baby bumps! Honestly, for bumpy skin like that, I'd suggest using a really gentle, fragrance-free baby wash, something like Cetaphil Baby or even plain water lang sometimes kaya na since baby skin is super sensitive. But tama, if the bumps aren't improving or parang nag-spread pa, better check with the pedia to make sure it's just heat rash or normal baby skin thing at hindi something else na kailangan ng specific care, kaya don't worry ha!
