The Philips Avent Ultra Air dummy is a breathable dummy for babies aged 6-18 months. It is equipped with extra large openings that allow the baby's skin to breathe, so that the skin does not dry out. The BPA-free orthodontic dummy set comes with a travel case that can be used as a sterilizer - just add some water and put the dummy in the microwave. The dummy will be clean and ready for next use. We asked moms how their little ones respond to our textured silicone dummies. On average, 98%* responded that their child accepts Philips Avent Ultra Soft and Ultra Air pacifiers. Everything in the Ultra Air dummy is designed for a feeling of light and comfort. This makes it easier for your child to suck on the pacifier and quickly get used to the change. We also focus on the healthy development of the baby's oral cavity by using a symmetrical dummy that adapts to the natural shape of the palate, teeth and gums. * Consumer tests conducted in 2016/2017 in the USA show that the Philips Avent ultra air and ultra soft corrugated pacifier is accepted on average in 98% of cases. ** For hygienic reasons, the dummies should be changed after 4 weeks of use.
