Considering we have a fussy baby who will only accept particular “dummies” these were a huge winner. You simply have to tip boiling / very hot water over the part they put in their mouths. You can quickly dip them in steriliser fluid provided you rinse them thoroughly

Something wrong with the shape, they don’t sit comfortably on face making it hard to suck well. And how silly to create a baby product that can’t be sterilised easily….

I found they left red marks on baby’s face as they are curved. They also can’t be used in an electric steam or microwave steriliser.
