What flow teat do these come with ?

Hi there, these come with the medium teat. If you would prefer a different flow, you can purchase the Boon Nursh Silicone Bottle Nipple 3pk. Here is a link to the product here: https://www.babyonthemove.co.nz/products/feeding-high-chairs/bottle-feeding/bottle-teats/boon-nursh-silicone-bottle-nipple-3pk/. Hope that helps
