After winter, we often receive inquiries from parents that their babies cannot hold their hands together, cannot roll over, etc. Through detailed understanding of the baby’s condition, combined with various objective laboratory tests such as the baby’s cranial nuclear magnetic field, the baby does not have any high-risk factors, and his or her development is quite good, except for his or her movement, which is slightly behind. Upon understanding that these children are wearing more clothes or are always being held, after improving these poor parenting situations and at the same time strengthening the training at home, the baby quickly catches up. This is a typical example of home parenting causing a baby to fall behind in motor development. There is also a baby, normal birth of a full-term baby, no high-risk factors, cranial nuclear magnetism is also normal, 6.5 months to sit unsteadily, the original parents are afraid of affecting the baby’s development of the cranial vertebrae, has been refused to allow the baby to sit, the physical examination found that the motor backwardness, only began to let sit, and do not dare to sit more than 6 months, every day to let sit for a few minutes. There are parents are afraid of hurting the baby’s neck, are four months still do not dare to vertical hold, the results of the baby’s head control significantly behind. Such examples are countless, the impact on the baby is not only reflected in the movement, but also in the intellectual and emotional development. A mother with a baby came to consult, this baby is the family’s second, full-term baby, perinatal situation is normal, the baby’s performance is the movement and intelligence are lagging behind the level of children of the same age, after understanding, it turned out that after the birth of the second baby, the adults at home for fear that the big baby is uncomfortable, jealous of the second baby, and therefore deliberately neglected the second baby, the second baby crying as a child is rarely picked up to comfort in the face of the big baby, but also try to kiss, less hugging, less teasing the two baby, and then slowly found that the second baby movement and the second baby, the second baby, and then the second baby, and then the second baby. The second baby is not as good as the first one, and then slowly realized that the second baby’s movement and intelligence and language are lagging behind the children of the same age. There is also a pair of twins, after birth by the grandparents and grandma and grandpa separately raised, the two children every month to another family to raise, due to the frequent change of surrogate caregivers, raising frequent changes in the environment, the baby needs to constantly adapt to the new environment, did not establish a good security attachment, the two babies have appeared to be behind in intellectual development and emotional instability, difficult to appease the performance. There are also cases of domestic violence, abuse and indifference in some families, which will also affect the baby’s development in various aspects. Therefore, in order for babies to grow up healthily, we should be full of love and understand the developmental characteristics of babies at different ages, follow the developmental rules, and provide a rich and suitable environment. If your baby’s development is lagging behind due to the family’s parenting environment, improving the parenting environment and strengthening the training at the same time will generally help your baby to make faster progress. If on the basis of improving the environment and strengthening training, the baby still does not make obvious progress, and the gap with children of the same age is getting bigger and bigger, then it may not just be a parenting problem, and should be further examined to find out the cause.
