  "title": "Why a Haakaa bottle nipple leaks and how to stop it",
  "question": "Why does a Haakaa bottle nipple leak, and how can the leaking be stopped?",
  "answer": "Haakaa Generation 3 Silicone Bottle Anti-Colic Nipple (S/M/L) - 2pcs: A flow rate too slow for the baby can build pressure behind the anti-colic vent and push milk out of the bottle neck, causing leaks; moving to the next flow level can fix it. To avoid leaking, push the nipple through the nipple ring, run a finger along the inside rim to check it is flat all round, and screw the top on straight and tight. Over-tightening the parts when assembling the bottle can itself cause leaks and may damage the ring.\nHaakaa Generation 3 Silicone Bottle Anti-Colic Nipple: Leaking during feeding can mean the nipple flow is different from what the child needs. Leaking can also happen if the silicone nipple is not sealed in properly; the nipple must be pushed through the nipple ring and the rim checked to be flat all around. Over-tightening the pieces while assembling the bottle can itself cause leaks. The three flows can be told apart by the hole at the teat tip: one small hole for slow flow, three small holes for medium flow and a criss-cross X shape for fast/variable flow. The ring should be twisted on only until resistance is felt, and no further.",
