Congrats sa first teeth, mama! For 1 year old, you can use a soft-bristled toothbrush designed for babies (like Pigeon or Nuby, maraming brands dito sa Watsons/SM), and for toothpaste, mas safe pa ang water lang or a rice-sized amount ng fluoride-free toothpaste kasi they still swallow most of it habang nag-eexplore pa lang sila. A few of us moms swear by just gentle brushing with water at making it playtime nalang para mahobby nila, then introduce proper toothpaste around 2-3 years na, the key talaga ay consistency, kahit gentle lang, every after meals or before bedtime para mastart na sila sa habit!
