Bought online, 9 yuan experienced four whole brain development classes. At that time, the baby went for the first time for 8 months, and the content was very rich. The baby is a little at a loss, some little tricks can't be done well, and the mother is a little depressed. The fourth time, the teacher said that he had made a lot of progress, and I was very pleased. Teachers always teach one-on-one with a smile. There are also brainwave music, flashcards, telling stories and training fine movements. The overall feeling is good, on the other hand, it also lets parents know how to guide their babies at home.
