Hi mommy! Those white stains could be from milk buildup or early fluorosis, so best to ask your pedia about it to be sure, they can check kung normal lang or needs adjustment sa routine nyo. For a one-year-old, silicone toothbrush is actually fine and safe, pero kung gusto mong mag-upgrade, you can try the soft-bristled ones designed for toddlers (like Nuby or Pigeon brands that many moms here use) since they're gentler on developing teeth at gums, just make sure the bristles are really soft and super fine para walang worry. Stick with your Tiny Buds toothpaste since fluoride-free and made safe for babies, at just use a pea-sized amount na hindi malalangap ni lo; honestly, brushing twice daily with the right technique matters more than the exact toothbrush model, so you're already doing great, first-time mom!
