Spill pads are used by breastfeeding mothers to protect their clothes from moisture caused by breast milk. Whether or not the pad is harmful to the baby actually depends on whether or not the mother changes the pad in a timely manner. If the milk is stored in the pad for too long, it will easily lead to bacteria growth. If the nipples are not cleaned in time, it may lead to bacteria growth on the nipples as well, which can easily affect the baby when he or she is breastfeeding and be harmful to the baby. If the mother often change the anti-overflow pad, at the same time, the nipple is reasonably cleaned, to ensure that the nipple hygiene in the case of the baby is not any harm, so the mother should pay attention to the usual timely replacement of the anti-overflow pad.
