Nipple cream is not recommended for breastfeeding without washing. Nipple cream is a type of cream that prevents nipples from cracking during breastfeeding. Usually, the main ingredient in nipple cream is lanolin or a greasy substance. However, some nipple creams contain vitamin E or hormones. If you breastfeed your child without washing it, it is easy for the child to inhale the milk and this may affect the child’s health. If you don’t wash the nipple cream and let your child suckle, don’t worry too much and observe your child’s reaction and gastrointestinal function in time. If symptoms such as diarrhea or vomiting occur, you should seek medical attention as soon as possible. Cracked nipples are a very common phenomenon during breastfeeding. If you are afraid that nipple cream is bad for your child, you can wash them before each feeding after use. If cracked nipples are severe, you should seek medical attention and treatment as prescribed by your doctor.
