Nothing really except some babies are allergic to latex. And some babies just don't like silicon. Every baby is different!!!!
Silicone based nipples, as opposed to latex nipples are easiest to clean and will not hold a bad smell.
Silicone bottle nipples are beneficial for feeding infants because they are durable, easy to clean, and resistant to heat. They also mimic the natural feel of a mother's breast, making it easier for babies to transition between breastfeeding and bottle feeding. Additionally, silicone nipples are less likely to cause allergic reactions compared to latex nipples.

Artificial nipples, such as pacifiers or bottle nipples, can impact breastfeeding for both mothers and infants by potentially causing nipple confusion. This confusion may lead to difficulty with latching and sucking at the breast, which can affect milk supply and bonding between mother and baby. It is recommended to avoid introducing artificial nipples in the early stages of breastfeeding to establish a successful breastfeeding relationship.
Some environmentally friendly alternatives to disposable bottle nipples for feeding infants include reusable silicone or glass bottle nipples, natural rubber nipples, and biodegradable or compostable bottle nipples made from materials like cornstarch or bamboo.
Pasties are patches that women put over their nipples to cover them and they are also attached with adhesive, and pasty is a baked pastry in form of a calzone.
