Hindi na ba advisable gumamit ng mga sippy cups dahil madalas pamugaran ng molds?

For me, ok pa din naman gumamit ng sippy cups especially if your baby is just learning how to drink on his own. Just make sure to check lead always, ung malapit dun sa silicon part kung saan dumadaan ung iniinom ni baby kasi according to the article I read, doon namumuo ung molds.
