Early education, the sooner the better. At the age of 0-6, that is, from the beginning of pregnancy, the effect is the best. The baby's growth starts from scratch. Since he was born, he began to accept the information transmitted to him by his surroundings. The first transmission of each kind of information will leave an indelible impression on the baby's mind, just like the first stroke we draw on white paper, no matter how we wipe it, it will leave traces. Therefore, the earlier you educate your baby, the more important it is, which will directly affect your child's future development in all aspects. Don't wait until the habit is broken.
Now there is an early education package called the cradle of genius, which is aimed at children aged 0-6. Your child is one year old now, so you can try this textbook. Many scholars say that this set of early education textbooks is very good. I just bought a set the day before yesterday and it hasn't arrived yet.
