Replace if It becomes Damaged
Just like all your baby’s items, pacifiers will undergo wear and tear. The nipple may tear or crack if washed improperly or if they are chewed on consistently by sharp little teeth. They can even deteriorate over time.
You should check the pacifier for damage before you give it to your child every time. Any damage or broken pieces can become potential choking hazards. If you notice any sort of damage or discoloration, you should throw the pacifier out immediately and replace it with a new one.
