Problem: Mrs. Melanie Weaver has made an appointment with the pediatrician for her six-month old daughter, Wendy. She wants to see the pediatrician about Wendy's growth and development, because she is concerned that Wendy is becoming too fat. She says, "Since Wendy started on solid foods a couple of months ago, she just got really huge! I think she's too big. Her legs are so chunky. My mother says she looks the way a baby should, but I keep hearing about childhood obesity. I've never been overweight a day in my life and neither has my husband. I wouldn't know what to do with a fat child."
