The feeding nipple is a boon to new born mothers. The ultra-soft silicone rubber with its double thickness ensures ideal softness and elasticity so your baby can latch on comfortably and easily. The shape fits perfectly onto your baby's tongue, allowing smooth tongue movement and minimizing air intake. The nipple's roomy base aids your baby in opening his mouth wide, encouraging steady peristaltic motion. You can choose latex, silicone, or rubber nipples. Latex nipples are softer and more flexible, but they don't last as long and some babies are allergic to them. Silicone nipples are firmer and hold their shape longer. You also have a choice in nipple shape – traditional, orthodontic, or flat-topped. Orthodontic nipples are designed to accommodate your child's palate and gums, and this type has a flat bulb on the side that touches your child's tongue. Flat-topped nipples are more like the shape of a mother's breast. Because you can't know beforehand which type or size nipple your child will prefer, it's best to play it safe and buy one of several types.
