10- 12-month-old baby focuses on training the control ability of baby's palm. Babies in this period, after early training, can basically have some independent palm control ability. You can let the baby throw the little things in his hand into a fixed container, for example, let the baby throw the balls into a glass bottle. You can also let the baby imitate adults and stir the objects in the cup with chopsticks. It not only trains the baby's control ability, but also trains the baby's movement accuracy.
