My daughter is a paci addict. The green soothies are the ONLY ones she will take. I guess as far as a paci goes, it's whatever shape the child prefers. Mine, just happens to loves these. Did I mention she is 3 now???? I'm ashamed to say that I have not gotten rid of it yet. She screams with delight when she sees them in the store, she cries all night if she doesn't have one. I guess if she was doing the review she would give them a hundred stars....
