  "question": "Can a protective silicone sleeve be added to a glass baby bottle?",
  "answer": "Haakaa Generation 3 Silicone Glass Bottle Cover: Made from 100% food-grade silicone. Compatible with Haakaa Generation 3 glass baby bottles. Lifefactory 4oz Glass Baby Bottle: The bottle comes with a silicone sleeve, polypropylene cap, ring, stopper, and Stage 1 (0-3 months) silicone nipple. The silicone sleeve protects the bottle from breaking when dropped; one parent reportedly dropped it on concrete with no chip. Lifefactory 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.",
