1, let's talk about the development of big sports first. The 7-month-old baby has sat firmly and can turn over, that is, turn over and turn over again. Parents can play rolling games with their babies to promote the development of their great sports ability. 2, the development of fine hand movements: the baby knows that he has two small hands and can grasp things with both hands. Some babies even do hand-handing, that is, handing things in one hand to the other, and the baby can also grab two things at the same time to knock, which is the symbolic action of the baby's fine motor development.

The 3.7-month-old baby begins to call mom and dad, which is of course unconscious, that is to say, the baby begins to pronounce the consonants "B, P, M" and so on, which is a sign of language development. At this time, parents should talk more about daily life language with their babies and identify daily necessities, such as refrigerators, televisions, tables, chairs, bottles and so on. Tell your baby the names of people and things and talk to your baby often. 4. In the baby's social development, a 7-month-old baby can see three meters away because of his visual development. At this time, he is close to an adult and can recognize his parents completely. Then, for strangers, the baby begins to dislike strangers hugging him, which is what we call the baby beginning to recognize strangers. At this time, it is necessary to establish the baby's sense of security. Parents can play hide-and-seek games with their baby, so that the baby can understand that it is not that the mother has disappeared for the time being, and develop the child's objectivity and permanence.
