I am seriously in love with these soothers. Not only do they soothe my baby but the fact that they are actually helping to encourage my baby's correct breathing is beyond amazing!! I also love that these ones are made from one piece of silicone, so I never have to worry about trying to clean in joins or pieces falling off. I think that it is really smart that this size has the addition of the gum massage ridge, to help my baby while they are teething. To anyone out there looking for a soother - you seriously cannot go past the Chicco soothers!!
