Baby requirements and preferences vary since they are different. Experiment with various forms and sizes to discover the ideal fit for your baby. The typical and standard recommendations are the sizes listed below. However, all sizes can be worn beginning at birth.

It all depends on what your baby prefers. Giving an infant a size three is not bad. However, given that the majority of babies like a smaller size, we have suggested the following:

  • 0+ months for size 1
  • 6+ months for size 2
  • 18+ months for size 3
  • One size for 0-3 years

All sizes can be used starting when your baby is born, and the age and size guidelines are merely meant to serve as a reference for you to follow.

When it comes to selecting the best pacifier, your baby’s physician and a family dentist can offer assistance and advice, but here are a few things you might want to take into account:

The pacifier’s design: The pacifier should ideally be made of one solid piece without any moving parts, a liquid inside, or integrated technology.

The pacifier’s dimensions: Select a size depending on your baby’s age. Additionally, pay attention to how big the shield extends from the nipple to the ring. It needs to be at least 1.5 inches in diameter to lessen the risk of choking.

The pacifiers’ construction: Additionally, stay away from any pacifiers that hook onto your baby’s crib, attach to their hands or neck, or cling to their body in any way.

Pacifiers exist in many sizes, just like clothing and bottles; however, it might not be as clear when your kid has outgrown his favorite pacifier as it is when he has outgrown his nicest pajamas. He might suck the shield and nipple into his mouth if the pacifier is too small, causing him to choke; if it is too big, he will spit it out.

You should choose the appropriate size pacifier based on your baby’s age regardless of the brand and kind of pacifier you decide on. For instance, different Philips Avent pacifier alternatives are divided into 0-6 months, 6-18 months, and 18+ months due to the variation in shield sizes. The extremely popular Philips Avent Soothie, which you probably received at the hospital, is available in two sizes: 0-3 months and 3-18 months.

When Do You Change Pacifier Size?

In general, you should follow the pacifier package’s age recommendations. Keeping a close check on your child’s use of the smaller pacifiers is important since a too small pacifier might cause choking. If your child refuses the larger pacifier, it is possible that he is not yet ready to move up.

Though your baby’s mouth is the same size (or bigger) as the pacifier shield, you should introduce the larger size pacifier even if your infant is not yet of the size change age.

Frequently Asked Questions

1. Does the size of a pacifier matter?

Yes. The ability of your child to hold the pacifier in his or her mouth properly is the most critical part. There is a definite difference in the shield size and the teat, particularly with the pacifiers for newborns, 0–6 months, and 6+ months.

2. Do you need to size up the pacifier?

The size is typically not printed on the actual pacifier, which is unfortunate, but paying attention is critical because using the incorrect size can result in choking. In addition to age, there are other indicators that it’s time to size up, such as the pacifier’s post-use imprint on your baby’s cheeks.

3. How to tell the size of a pacifier?

For infants of various ages, pacifiers are available in various sizes. Onesize for 0-3m, size 1 for 0+m, size 2 for 6+m, and size 3 for 18+m. Use the pacifier according to the recommended age range at all times because an older infant could be able to fit one designed for newborns in their mouth and choke.

4. When to change pacifier size?

Even if they are connected to a specific binky, not all children will accept your pacifier change. However, you’ll size your child again by the time they’re six months old. After one year, there is a different size for children up to three years old.

5. What size pacifier do I need?

Depending on your baby’s age, select a size. Additionally, pay attention to how big the shield is that extends from the nipple to the ring. It needs to be at least 1.5 inches in diameter to lessen the risk of choking.

6. Can a 6-month-old use a 0-3 month pacifier?

A pacifier that fits a newborn will be too tiny for a 6-month-old because babies develop so quickly.

7. Can a newborn use a 6-month pacifier?

You can start giving your child a pacifier as early as three months or six months old. Pacifiers can be used from birth at any age.

Conclusion

The ideal pacifier is the one your child prefers. Sizing plays a crucial role. There are also certain strategies you may employ to raise the likelihood that your infant will enjoy the pacifier you select for him or her. Whatever pacifier you decide on, be sure the nipple has adequate ventilation. According to some pediatric dentists, Pacifiers without this airflow may impair a baby’s developing palate.

Most pediatricians concur that a baby doesn’t notice too much of a difference in the shape of “orthodontically” touted pacifiers. But if buying one of these pacifiers makes you feel more at ease, just look at the packaging to see the specifics of the design.

Additionally, you want to check that your pacifier is secure and primarily constructed of natural materials. The risk of choking when using pacifiers can be significantly decreased by ensuring that your pacifier is manufactured out of a single piece of solid plastic. Additionally, you want to ensure that the pacifier you select is BPA-free and manufactured entirely of silicone (as far as the nipple is concerned).
