Baby Bottle Nipples Sizes

Deciphering what baby bottle nipple level to purchase can be a little confusing, which is why we created a helpful guide. Here are the bottle nipples available on Amazon, their corresponding size and age guidelines, and some pros and cons to each.

It may come as a surprise that baby bottle nipple levels actually refer to the size and flow of the nipple opening, and not the nipple itself. There are varying degrees of nipple flow that can be described as slow, medium or fast. Depending on your baby’s age and feeding style, you may need to size up or down from the starting nipple level of “slow.”

Unfortunately, there’s no easy way to know which bottle nipple level is correct for your baby. However, we’re always here to help you make the right choice. Please give us a call at or email us at [email protected]

It’s easy to feel a little confused when you’re faced with options like “slow flow”, “medium flow”, and “fast flow”. When do you move up or down? We’re here to explain these baby bottle nipple levels!
