What should I do if my baby is crying, has blood in his stool, or is bloated?

Question 1: My baby is 45 days old and I am breastfeeding. I have frequent flatulence and crying recently. I had bleeding in my stool today. What should I do? Dr. Cui Lixia’s answer: If the child is not uncomfortable with flatulence, there is no need for intervention and the child can adjust it by himself. Crying may be due to stomach discomfort. If there is bleeding in the stool, it is recommended to go to the hospital to check the stool. Let the baby defecate directly into a disposable paper cup or a clean plastic bag, and send it to the hospital for examination within an hour. Question 2: My baby is one year and eight months old. When the weather gets cold, he will grunt and breathe heavily, as if he has phlegm. It would be nice to take a breather now and then, as the weather warms up. When a child is born with hypoplastic laryngeal cartilage, what should I do? Dr. Cui Lixia’s answer: Based on your description, I think it’s cold air allergy. The best way is to avoid catching cold and avoid going out when the temperature is low in the morning and evening. The baby\’s laryngeal cartilage is underdeveloped, and the tracheal spasm is prone to panting when exposed to cold. Mild congenital laryngeal chondrodysplasia usually resolves around half a year old, while severe cases may not resolve until around 2 years old. Question 3: The mother has three positives of hepatitis B, and the baby cannot receive the second dose of hepatitis B vaccine due to jaundice one month after birth. Will delaying vaccination of hepatitis B vaccine affect the blocking? Can I breastfeed in this case? Dr. Cui Lixia answered: Hepatitis B immunoglobulin has a blocking effect, but hepatitis B vaccine does not. If the baby\’s liver function is normal, it does not affect the hepatitis B vaccine. To determine whether breastfeeding is possible, you need to first check the mother\’s hepatitis B virus DNA replication. If there is replication, breastfeeding is not recommended.
