因为工作原因,儿子断奶后一直放在老家给婆婆带。现在,我们把他接回来上小学,但发现他有很多坏习惯,和我们也不亲近。为此,我们努力了半年多,收效不大。听说孩子3岁前的关键期如果没和父母在一起,以后将无法弥补,是这样吗?我们该怎么办? Because of work reasons, the son has been placed at home to give her mother after weaning. Now, we took him back to elementary school, but found that he had many bad habits and was not close to us. To this end, we worked hard for more than six months, with little success. I heard that the critical period before the age of 3 children without their parents, the future will not be able to make up, is it? What should we do?
