  "question": "Which baby bottles weigh the least for carrying in a diaper bag?",
  "answer": "Comotomo COM150TPKIT1: The maker lists the 5 oz bottle at 0.32 lb (147 g); this is the bottle specification, not a stated four-pack weight. Each bottle holds 5 oz (150 ml).\nComotomo COM250TPKIT1: The maker lists the 8 oz bottle at 0.38 lb (170 g) each; the store rounds this to 0.4 lb. Each bottle holds 8 oz (250 ml) and measures 2.56 inches wide by 5.12 inches high.\nDr. Brown's WB92028: The listed variant weight is 277 (likely grams). The product is a 2-pack of Dr. Brown's Natural Flow Anti-Colic Options+ wide-neck baby bottles, 9 oz/270 mL, with Level 1 slow flow nipple.",
