My daughter never wanted to have another pacifier, she likes to turn to as she has him in the mouth on the ring. We got such a model in the hospital because she was a premature baby and this nipple was nice small for her delicate little mouth. Other brands do not accept. It has almost 3 years is still the size of 1 is a good thing, because then the cleaner does not fill your mouth so much out that there could be damage. I do not know why you only get the so-called orthodontic shape? Some of which are far too big. She takes him only to fall asleep. Recommended!
