At what age does it become normal for a baby to turn over? Not being able to crawl or turn over turned out to be my fault…

Question 1: During the 42-day review of the baby, our county hospital said that the baby’s muscle tone was high and that he needed rehabilitation. Then we went to Zhengzhou Maternal and Child Health Hospital to see that the baby’s muscle tone was not high, so we came back. The baby is now four months old. He can raise his head and do everything fine. I don’t know whether it’s because he is a little fat or because he wears thick clothes. He still can’t turn over. Also, when I ask him to stand up, his two toes always point. Is something wrong? Dr. Luo Zhen’s answer: If there is no problem with muscle tone, don’t worry. If the baby cannot turn over, it is very likely that the parents have made the baby wear too heavy clothes, which affects the normal activities of the baby. The baby is naturally unwilling to move when he is restrained, which inadvertently causes the phenomenon of lagging behind in motor development. Secondly, overweight babies lag behind in learning to turn over, because the baby is heavy, clumsy, and has less strength. Even if the baby wants to turn over, there are various resistances that make the baby unwilling to practice turning over or even give up. Therefore, parents should pay attention to more guidance and exercises for babies to turn over. It is recommended that the baby be placed on a small sheet, with two parents standing at one end, holding the sheet, and rolling the baby left and right, so that the baby can turn over as a game. Note that it should be done on the bed at home, or on the floor protected by a mat. Another method is: when the baby is lying down, the parent stands on the side of the baby and gently pulls the baby\’s distal hand toward you until the baby is pulled into a side-lying or prone position. Question 2: Hello doctor, my baby girl is two years old. Two lymph nodes that can be rolled can be felt behind the left ear. They are about the size of mung beans. They can also be felt under the back of the head. They were first discovered in June. At that time, I went to check the blood test. It was a little high and it took three days to take azithromycin and it came down. , but the lymph nodes are still so big. Later, it gradually became smaller, and recently it was discovered that it was as big as it was at the beginning. She had a cold before, but she is better now. I would like to ask the doctor why the lymph nodes grow repeatedly? what to do? Dr. Sun Cuiying’s answer: It is recommended to do another blood test to see if there is still inflammation. If it is just simple swelling, it is recommended to observe whether there are other symptoms. If not, pay more attention to maintenance. Question 3: My 40-day-old baby has bloated stomach. Can I take Mommy Love probiotics? We haven’t vaccinated yet~ Dr. Cui Lixia answered: The vaccine can be vaccinated. If the child has no discomfort, is breastfeeding and has normal bowel movements, there is no need to intervene or take probiotics.
