Sucking is an innate way of babies. In addition to crying, parents often see babies sucking on their nipples but not breastfeeding or sucking their fingers. This is actually the baby comforting himself. Just sucking your fingers can easily cause a large number of bacteria to enter the body from the baby's mouth, causing discomfort to the baby. At this time, you should consider using a pacifier for the baby, which can not only avoid the invasion of bacteria, but also soothe the baby's anxiety and let the baby suck. Fully enjoy the joy of "soothing"!
