The development of the child’s intelligence mainly depends on the age distribution of the child, for the newborn baby, we have to give him frequent touch. After the full moon you can do baby passive exercises, you can give your baby audio-visual training, show him black and white cards, red balls, listen to rattles, listen to soothing music. All these ways can be done at home and are better practices to promote your baby’s intellectual development. As the child grows older, we need to talk and communicate more with the child, thus promoting the child’s language and cognitive development, and helping the child with gross motor development such as prone head lifting, turning over, sitting, standing, crawling, walking and jumping, all of which help the child’s intellectual development. After the baby is older, we can also give the child parent-child activities in the formal maternal and child health institutions, parent-child courses help to enhance the relationship between parents and children, but also help the early development of children’s intelligence.
