your son needs to be examined by his pediatrician or a pediatric urologist. sometimes there are congenital anomalies of the penis that will place the urethral opening too high or too low (such as hypospadias). or he could have some urethral adhesions that can be easily fixed. i am not sure which way he is urinating (up down sideways? ) but i would have to say this is "not normal". get it checked out.
my 6yo son urinates at a 45degree angle and has since birth is this normal or is there an issue?
