General Information: During the bottle feeding period, the nipples used vary depending on the month of the baby. Among the issues that mothers pay most attention to when it comes to pacifier models is that the pacifier tip resembles the mother's nipple and that the baby feels comfortable while feeding. At this point, Wee Baby Bottle Pacifiers will be the ideal choice. Bottle teats designed by imitating the mother's nipple provide a natural nutrition similar to that of the mother's breast. Round-Tipped Bottle Pacifier No: 1, one of the pacifiers that offers 3 different flow sizes, allows newborn babies to be fed comfortably by providing a low flow.
