Baby hiccups, also known as diaphragmatic spasms, are mostly caused by babies swallowing too much air while breastfeeding. Hiccups are very common in babies and there is no need to worry. Baby hiccups can be solved in the following ways: 1. Use the right way and method when feeding. Breastfed babies cannot just stuff the nipple into the baby’s mouth when eating milk, the correct method should be to stuff the areola into the baby’s mouth. This way the airtightness will be better and the possibility of air being swallowed is relatively small or less in quantity. Bottle-fed babies should have their nipples filled with milk and not have a mixture of milk and air when they are breast-feeding.2. You should burp your baby after breast-feeding by gently patting your baby’s back, head up and feet down, for 15 minutes to half an hour. 3. If the above measures do not work, you can also give your baby some hot water, which usually relieves it.
