Ah, super common question yan! Honestly, I've seen a lot of mums sa group namin using Philips Avent bottles para sa storage, they're sturdy, madaling i-label with dates, at hindi sira agad even after matagal na. Ang iba naman swear by Tommee Tippee or Medela bottles if you want something mas specific for breastmilk. Check mo sa major drugstores like Mercury Drug, Watsons, or baby shops sa mall, sigurado may available, at pwede mo ring i-compare ang prices online vs physical stores before bumili!
