When To Switch To The Next Nipple And Pacifier Size

It can often be difficult to know when to change to the next size of your baby’s pacifier. In fact, some parents don’t even realize that they need to change at all! If you take a close look at your pacifiers’ packaging, however, you’ll notice that there is a size – usually 0-3 months, 0-6 months, 6-18 months, etc. Unfortunately, most pacifiers don’t print the size on the actual pacifier, but because the wrong size can be a chocking hazard, it’s important to pay attention.

“Besides age, there are some signs that it’s time to size up – like that the pacifier leaves an imprint on your baby’s cheeks after use,” says Dr. Neela Sethi MD, practicing pediatrician and lactation consultant. “Also if your child seems to dislike the pacifier all of a sudden, this can be a clue that the pacifier is too small. Lastly, if your child cannot keep the pacifier in their mouth despite trying (i.e. they show a desire to have the pacifier, but it will not stay in), this is another sign to switch to a larger size.”
