We have also received the Goldi sucker recommended and I must say that our daughter (2 months, breastfeeding child) no longer want other pacifiers and no "nipple confusion" occurred. That the sight first time getting used to, with this great "pacifier plate" is clear, however, the babies get very comfortable very good air. Consider times just how babies get air to the chest. That works, too. In addition, the pacifier can not be "fixed sucked" through this form. Our daughter took the pacifier from the beginning.
