Summarize this article:

Doctors use the major and minor criteria to determine if Prader-Willi Syndrome is a possible condition for your child. Looking for these symptoms can help you determine if your child should be tested or examined by a doctor.  For children two and under, a total of five points is needed to be tested. Three to four points must be from the major criteria symptoms, with the others coming from the minor symptoms. Children three and over must score at least eight points. Four to five points need to be from the major symptoms. One good way to get your child diagnosed for Prader-Willi Syndrome early is to take them to their scheduled check ups after they are born. The doctor can track their development and start to notice any problems. During any of the visits during your child’s early years, the doctor may use the symptoms noticed during the exam to diagnose PWS.  In these appointments, the doctor checks the child’s growth, weight, muscle tone and movement, genitals, and head circumference. The doctor also routinely monitors the child's development. You should tell the doctor if your child has problems eating or sucking, if there are problems sleeping, or if they seem like they have less energy than they should. If your child is older, tell your doctor about any food obsessions or habits of overeating you notice in your child. If the doctor suspects PWS, they will perform a genetic blood test. This blood test will confirm that your child has PWS. The test will look for abnormalities on chromosome 15. If there is a history of PWS in your family, you can also get prenatal testing to check your baby for PWS. The genetic test can also help you figure out if you may have other children with the same condition.

Summary:
Know when to seek medical help. Take your child to the doctor. Get genetic testing.
