Body Mass Index (BMI). Body Mass Index (BMI) is measure of body fat based on height and weight that applies to both adult men and women. BMI does not differentiate between body fat and muscle mass. Therefore, body builders and people who have a lot of muscle bulk will have a high BMI but are not overweight or obese.
The bump: or hematoma as we call it, can last for 1-2 weeks. Sometimes it gets slightly worse before it gets better. If the child is acting normally, and not vomiting uncontrollably, she should be fine. If she starts doing those things, call your pediatrician.
If your child or someone you know has sustained a head injury, observe them closely for 24 hours to monitor whether their symptoms change or get worse. If you've sustained a head injury, ask a friend or family member to stay with you for the next 24 hours to keep an eye on you. If your child has a minor head injury, they may cry or be distressed. This is normal â with attention and reassurance most children will settle down.
