  "title": "Protecting a Glass Baby Bottle From Breaking",
  "question": "How can a glass baby bottle be protected from breaking?",
  "answer": "Lifefactory 4oz Glass Baby Bottle: The silicone sleeve protects the bottle from breaking when dropped; one parent reportedly dropped it on concrete with no chip. For freezing, store upright, do not fill to the top, and leave at least 2oz/58 ml of open space from the neck to allow for expansion and prevent glass breaking.\nLifefactory 9oz Glass Baby Bottle: Feedback was mixed: users liked the glass construction, silicone sleeve and perceived quality, but the narrow opening was a major drawback. The borosilicate baby bottle can transition from the freezer to boiling water.\nDr. Brown's Anti-Colic Options+ Narrow Glass Baby Bottle: The glass bottles are heat and thermal shock-resistant and can withstand hot and cold temperatures and gradual temperature changes.",
