Hindi ako personal user ng Mustela, but a few of my mum friends swear by their products for sensitive baby skin, gentle and walang harsh chemicals na makakasama sa delicate skin ng babies. That bundle looks convenient kung gusto mo ng complete set, though honestly nag-start lang ako with basic baby wash at lotion para makita kung ano ang best for my baby's skin type, then nag-add from there. For newborns especially, mas better kung minimal muna ang products, then you can always upgrade once you see how your baby's skin reacts!
