When a newborn baby is crying and not sleeping, first of all, you need to look for the specific reason to see if the baby is not full, you can try to feed breast milk or add milk powder to observe it. If the baby no longer cries and can sleep peacefully after eating formula or drinking breast milk, the situation is considered to be related to hunger. If the baby is still in a crying state after eating formula or drinking breast milk, you need to see if there is bowel movement or abdominal discomfort, you can try to warm the tummy with a warming bag, because this situation needs to exclude whether there is intestinal cramps. The newborn is usually seen to be crying more severely and difficult to soothe, mostly related to the abdominal cold, can take oral probiotics and other drugs to regulate it.
