Babies that experience failure to thrive may have Prader-Willi syndrome. This means that they do not grow at the same rate as their peers and may be malnourished. Most often, this is a result of an inability to feed properly. Many infants with this symptom have a weak sucking reflex, leaving them unable to get enough nourishment regardless of how they are fed. This reflex may be deficient in part because of the poor muscle tone that often accompanies this condition. Failure to thrive is a serious symptom, and you should seek medical attention if you notice that your child is not gaining weight.
