Hindi ko sure kung ano exactly ang tanong mo about toothpaste and shampoo related sa human nature, hehe, pero if you're asking kung paano pumili ng safe products for your kids or family, that's something we moms think about a lot! A few of us try to go for gentler brands, especially kung may sensitive skin or allergies in the family, kasi parang reflection din yan ng pagmamahal natin sa loved ones, no? If you can clarify what you meant, I can give you better advice!
