Philips Avent ultra air soother is a Breathable, BPA-free soother for babies aged 6-18 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 soother set comes with a travel case that doubles up as a steriliser, so all you need to do is add some water and pop it in the microwave. Then rest easy that it's clean for the next use.
