Honestly, I waited until my baby was around 3-4 months old before using lotion, pero it really depends on baby's skin, kung napakadry or may patches na rashes, you can start earlier with a gentle, fragrance-free lotion designed specifically for newborns. Para sa peace of mind though, better to check with your pedia first, especially kung first time ka lang, para ma-rule out kung may skin condition na kailangan ng special care instead ng regular lotion!
