I feel that these early education machines are very extravagant, and their effects on children are not as good as we thought. Since we want our children to receive early education, as parents, we should first understand some knowledge about prenatal education, early education and parenting, and educate our children with scientific and professional knowledge. Instead of buying a cold machine and letting them face the machine, we should buy toys to develop their intelligence, which can make them play happily and develop their children. Being smart can also give children a wonderful childhood, so as a new generation of parents, they are always blind in educating their children and know little about parenting knowledge and common sense.
