Sometimes you need to search and try a little to find the ABSOLUTELY right pacifier for baby. BIBS pacifiers are divided into the age categories 0-6 months (size 1), 6-18 months (size 2), 18 months+ (size 3) - as well as one size (De Lux). However, it is important to note that all children are different - and many thrive best with a size 2 pacifier from the start. Try out the sizes in our wide selection. Skjul
