If the baby\’s thumb is bent but not stretched, how to judge whether it is abnormal?

Question 1 Why does the baby keep having diarrhea on the fifth day after birth? Dr. Yang Yafeng answered: Diarrhea generally includes infectious diarrhea and non-infectious diarrhea; allergic diarrhea and breast milk diarrhea. Breast milk diarrhea is more common in infants, especially those who are lactose intolerant. If the baby sleeps well and is in good spirits, you can continue to observe and continue breastfeeding, as long as he is not dehydrated; if he has diarrhea after eating breast milk, the frequency of diarrhea is relatively high, and his sleep is poor, it may affect the growth and development of the child, and treatment is required at this time. You can take some probiotics first and observe. If the effect is not good, you can stop breastfeeding, switch to artificial feeding, and give lactose-free milk powder. For breast milk allergy diarrhea and lactose intolerance diarrhea, lactose-free milk powder can be given. The effect will be seen in two or three days, and then mixed feeding can be done. Question 2: My baby is more than 2 months old and almost 3 months old. His left thumb is bent and cannot straighten on his own. He can straighten it. After straightening, it can bend normally. There is no pain for the baby when he cracks his fingers. He can return to the original shape after squeezing his fist. This what\’s going on? Dr. Luo Zhen answered: This situation is normal. Generally, the baby can stretch out actively at four months. As long as the baby can stretch out and pick up things when the time comes, there is no need to worry. Question 3: The baby is 3 years old and 7 months old. In the past two days, he has been complaining of stomachache. His stool is normal, not dry, moist and a little sticky. He also eats some food. He had food accumulation and gastrointestinal problems before. I went to the hospital to see a doctor. The doctor touched my stomach and said it was due to the season. When I came back, I still complained of pain. Is there any solution? Dr. Cui Lixia answered: If the pain is around the belly button, it will be fine after a while. It is recommended to check the abdominal B-ultrasound to see if there is mesenteric lymph node enlargement.
