This is a size L pacifier suitable for babies 6 months and older. I bought it in a hurry two days ago when my baby started fussing while we were out, but they didn't want it and didn't use it at all. It has been sterilized, but please purchase only if you are not concerned. *It hasn't been used at all, so there are no bite marks. It comes with a pacifier cap. Thank you for looking.
