Sold in a range of colors and patterns, pacifiers are the “it” accessory in the under one crowd. But they’re also essential to new parents: They can help calm down a baby and even help support safe sleep habits, according to the American Academy of Pediatrics.

While the brand you buy is up to you, there are some safety things to note: A pacifier should be one piece (two piece models can be a choking hazard) and should be designed for your baby’s size—some models are made specifically for younger or older infants. Here are our picks.
