  "question": "What steps should a parent take if a glass baby bottle cracks or breaks?",
  "answer": "The checked facts do not give steps for a cracked or broken glass bottle, such as replacement or disposal. The related facts on protection and care are below. 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. Lifefactory 4oz Glass Baby Bottle: 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. Lifefactory 9oz Glass Baby Bottle: The bottle is made from thermal-shock-resistant borosilicate glass. Dr. Brown's Anti-Colic Options+ Narrow Glass Baby Bottle, nipple guidance only: Discontinue use and replace the nipple immediately if any signs of wear or damage are visible, such as cracking or change of shape.",
