  "question": "How should a nipple be measured to choose the right Munchkin nipple shield size?",
  "answer": "Munchkin Nipple Sizing Tool: The maker says to measure the nipple before feeding, while it is stimulated. The measurement is the nipple diameter at its widest point, with the areola left out. The maker says the right hole size is the one whose circle edge comes close to the base of the nipple without touching it.\nMunchkin Flow Nipple Shield +: For best sizing results, measure the nipple when it is stimulated. A nipple diameter up to 15mm corresponds to the small 16mm shield.\nMunchkin Flow Nipple Shield+ Bundle: Size is chosen by measuring the nipple diameter at its widest point, excluding the areola, and measuring while the nipple is stimulated is recommended for best results. The shield comes in four sizes: small 16mm, medium 20mm, large 24mm and extra-large 28mm.",
