It's important that your baby can easily keep the pacifier in their mouth. Especially with different sizes of pacifiers, such as the Newborn, 0-6 months, and 6+ months variants, there is a clear difference in size between the shield and the suction part.
Some signs that your baby may struggle to keep the pacifier in their mouth include:
- Visible effort in holding the pacifier
- Quickly spitting out the pacifier
- Imprints of the shield on your baby's cheeks
If you notice one or more of these signs, it's wise to switch to a larger size pacifier.
