♂? Moderate fitness
The simplest and most effective way is to do proper fitness exercise! For example, doing push-ups is a very good choice, which can not only help improve chicken breasts, but also make children feel confident and happy.
Sleep well
When sleeping, you can put a bran or a bran pillow on the child's chest to let the child sleep on his back, which helps to avoid the deformation of bones during development.
Healthy diet
Diet is also very important. As long as a healthy and reasonable diet is guaranteed, there is no need to over-supplement nutrition.
