I wanted to try the NUK Newborn 100% Silicone Pacifier for my newborn Grandson he came home from the hospital with the same one but it had the regular nipple shape and it seemed that it was a little hard for him to keep it in his mouth especially at night when he rested his mouth in between sucking on the pacifier, not that he always sleeps with it at night but sometimes he just needs it when we know he just ate and the diaper is changed and just needs soothing. The shape is more like a natural shape and fits better in the mouth. I love the the pacifiers are BPA-free I wouldn't buy anything that isn't 100 %. I also like that they are one piece so never have to worry about any pieces falling apart and no place to get dirty in the crevices so it's easier to make sure it is clean. My Grandson had a hard time latching on to mommies breast when feeding and lost some weight when he was first born so I think that giving him the pacifier has helped him strengthening his sucking and now he doesn't have any problem, so to the mothers who say I'd never give my baby one there is a good reason that the doctors recommend them to. Anyway my Grandson loves and I would recommend them to any parent who is looking for one.
