Difrax pacifiers keep pace with your child's development. We distinguish 5 age groups: New-born for newly born and premature babies, 0-6 months, 6-12 months, 12-18 months and 18 months and over.
The shield becomes bigger and the nozzle is designed to fulfil your child's suckling reflexes. As your baby gets older, the sucking part becomes sturdier. Eventually, the sucking part of the 18+ pacifier is completely solid.
