When a baby is born, they have a powerful sucking reflex that allows them to breastfeed without any difficulties. You may have seen an ultrasound picture of a baby sucking their thumb while still in utero. From this very early age, the act of sucking is soothing to your baby, and the use of a pacifier can help calm them.
There are different types of pacifiers and products that resemble pacifiers for older babies beginning to teeth. There are a few differences between the products, including when best to use them.
Pacifiers are intended for your baby to suck on like they would a breast or bottle. Pacifiers aren't designed to be chewed on. If your baby chews on a pacifier, they can accidentally bite a piece off, creating a choking hazard.
Teething pacifiers are made with a much harder material that is often solid. They are designed to hold up even when a baby with a few teeth starts chewing on them. Teethers are more challenging to suck on, so they aren't as good at soothing babies as pacifiers.
