Silicone latex for baby pacifiers, which will be better? Let the baby try it first, and then decide what material to choose according to the baby's preferences. In addition, because the nipple is repeatedly heated and disinfected during use, both the latex nipple and the silicone baby pacifiers are consumable. The new nipple is replaced in about one month, and the new nipple is replaced in about two months. If cracks are found in the nipple or stickiness begins to develop, a new nipple should be replaced immediately.
