Hi,
     On the topic of pyloric stenosis we just had a mother whose baby was
diagnosed with pyloric stenosis at 2 weeks of age.  This is not too early.
Projectile vomiting is pyloric stenosis or some other type of atresia of the
digestive track until otherwise specified.  Recommending that they see or
speak directly to the pediatrician is the right advise.
