Philips Avent ultra air pacifier is a breathable pacifier for babies aged 0-6 months old. It comes with extra-large air holes that let your baby's skin breathe, meaning the skin remains dry. The orthodontic and BPA-free pacifier set comes with a travel case that doubles up as a sterilizer, so all you need to do is add some water and pop it in the microwave. Then rest easy so that it's clean for the next use.
