What is the best support a normal family can give to their children?

Before development is complete:
1. If you have money, eat more beef and lamb; if you're short on cash, eat more pork, duck, and chicken; if you really can't afford it, eat more eggs—five a day costs less than five yuan.
2. Help them develop good sleeping habits—unconditionally go to bed at 9 PM; if they can't finish their homework, tell them to forget it. Growing 10cm taller is a thousand times more important than those useless elementary and middle school homework.
3. Pay attention to their dental, jaw, and posture development, and correct issues promptly.
4. Engage in plenty of outdoor sports. Take them outside often, and during puberty, challenge their physical limits as much as possible.
5. During adolescence, focus on skincare and avoid leaving acne scars on their face.
