Of course it is necessary. My son has been studying in a parent-child class, but I decided to find a parent-child class closer to home. You don't need to go to any Oriental Baby, there are many distinguished people. My son was the first to study in Oriental Baby. He is much older and far away from home. Later, he found a parent-child class close to home, with few people and similar teaching. There are also group purchases online, and the price is reasonable! It makes a big difference whether the baby goes to the parent-child park or not. Some Bao Xiao won't go. When he arrived in kindergarten, he was slow to reflect and accept things, and he was unsociable. It is really necessary. Believe me, my son is 4 years old, and now he is not afraid of strangers. Very good! !
