A related discussion,
homone shots was started.
There may be a serious hormonal problem or even a complicated chromosonal make up of your child. You need to get him to a doctor as soon as possible because sometimes , if it is hormonal, additional hormones can help your child have a normal growth pattern. So please see someone and find out exactly what is happening.
umm.. take him to the drs of course.
Id talk to his Pediatrician about it. Does he show any signs of growth disorder besides what you have mentioned? (height, feet, arms, ect?)
Maybe he'll just be a small dude.
