It is normal. Most children are much more energetic than us adults. Shouting and jumping are all ways for children to vent their energy. In the past, our children were so energetic that we couldn't stand the noise. Later, I reported to him about Gymboree's early education. The teacher told me not to underestimate the children's screaming and chasing. This is also a sport. In the game, the children fled and chased excitedly. At this time, screaming is a unique way for children to deal with emotions. So the teacher suggested that I play with my children, don't interrupt them, don't criticize them, communicate with him with my heart, and gradually the children can control their emotions. I suggest that if you have time, you can take your baby to Gymboree to feel it. It's really good. Now Gymboree has a year-end thanksgiving ceremony, which is a rare opportunity ~
