but some may weigh more and some less. but very quickly, a baby gains weight and everyone is glad about that because it means the child is growing bigger and stronger.as you get older, your weight is still important. its something your parents and doctor will probably keep an eye on. when you go for a checkup, the doctor often records your height and weight and compares it with what it was the last time you came in. the doctor wants to check whether you have a healthy weight because weighing too much or too little can be a problem.but these days, being overweight is more common than being underweight. in the last 30 years, a growing number of kids and teenagers have developed weight problems. today, 1 out of 3 kids and teens between the ages of 2 and 19 are overweight. many grownups understand what its like to have weight problems, since 2 out of every 3 adults are overweight.for kids and adults, weighing too much can lead to illnesses and health problems. and a kid who is overweight might be made jokes on or find it hard to keep up with friends on the playground. when people talk about being overweight, they mean that someone has more body fat than a healthy one. everyone has some body fat, but extra(多余的) fat can influence peoples health and ability to walk, run, and get around, as well as how the person looks and his or her selfrespect.语篇解读：本文是一篇说明文。自从你出生的那天起，你的体重对你来说就很重要。本文主要介绍了超重现象及其带来的问题。5why is everyone happy hearing a baby become fatter?athe baby is growing healthily.bthe parents are rich enough.cthe mother has
